 ### PR Format
 
-We use [waffle](https://waffle.io/) for project management, and it will automatically keep us organized if you do one simple thing:
-
 If this PR closes the issue, add the line `Fixes #$ISSUE_NUMBER`. Ex. For closing issue 418, include the line `Fixes #418`.
 
 If it doesn't close the issue but addresses it partially, just include a reference to the issue number, like `#418`.
 
+Submit your PR against the `develop` branch. This is where we merge new features so they get some time to receive extra testing before being pushed to `master` for production.
+
+If your PR is a hot-fix that needs to be published urgently, you may submit a PR against the `master` branch, but this PR will receive tighter scrutiny before merging.
+
 ## Before Merging
 
 Make sure you get a `:thumbsup`, `:+1`, or `LGTM` from another collaborator before merging.

+## txMeta's & txParams
+
+A txMeta is the "meta" object it has all the random bits of info we need about a transaction on it. txParams are sacred every thing on txParams gets signed so it must
+be a valid key and be hex prefixed except for the network number. Extra stuff must go on the txMeta!

+Here is a txMeta too look at:

The most current version of these Terms will be posted on our Site. You shall be responsible for reviewing and becoming familiar with any such modifications. Use of the Services by you after any modification to the Terms constitutes your acceptance of the Terms of Use as modified.\n\n\n\n## 3. Eligibility ##\n\nYou hereby represent and warrant that you are fully able and competent to enter into the terms, conditions, obligations, affirmations, representations and warranties set forth in these Terms and to abide by and comply with these Terms.\n\nMetaMask is a global platform and by accessing the Content or Services, you are representing and warranting that, you are of the legal age of majority in your jurisdiction as is required to access such Services and Content and enter into arrangements as provided by the Service.

MetaMask encrypts this information locally with a password you provide, that we never send to our servers. You agree to (a) never use the same password for MetaMask that you have ever used outside of this service; (b) keep your secret information and password confidential and do not share them with anyone else; (c) immediately notify MetaMask of any unauthorized use of your account or breach of security. MetaMask cannot and will not be liable for any loss or damage arising from your failure to comply with this section.\n\n## 5. Representations, Warranties, and Risks ##\n\n### 5.1. Warranty Disclaimer ###\n\nYou expressly understand and agree that your use of the Service is at your sole risk. The Service (including the Service and the Content) are provided on an \"AS IS\" and \"as available\" basis, without warranties of any kind, either express or implied, including, without limitation, implied warranties of merchantability, fitness for a particular purpose or non-infringement.

Binding Arbitration and Class Action Waiver ##\n\nPLEASE READ THIS SECTION CAREFULLY – IT MAY SIGNIFICANTLY AFFECT YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO FILE A LAWSUIT IN COURT\n\n### 13.1 Initial Dispute Resolution ###\n\nThe parties shall use their best efforts to engage directly to settle any dispute, claim, question, or disagreement and engage in good faith negotiations which shall be a condition to either party initiating a lawsuit or arbitration.\n\n### 13.2 Binding Arbitration ###\n\nIf the parties do not reach an agreed upon solution within a period of 30 days from the time informal dispute resolution under the Initial Dispute Resolution provision begins, then either party may initiate binding arbitration as the sole means to resolve claims, subject to the terms set forth below. Specifically, all claims arising out of or relating to these Terms (including their formation, performance and breach), the parties’ relationship with each other and/or your use of the Service shall be finally settled by binding arbitration administered by the American Arbitration Association in accordance with the provisions of its Commercial Arbitration Rules and the supplementary procedures for consumer related disputes of the American Arbitration Association (the \"AAA\"), excluding any rules or procedures governing or permitting class actions.\n\nThe arbitrator, and not any federal, state or local court or agency, shall have exclusive authority to resolve all disputes arising out of or relating to the interpretation, applicability, enforceability or formation of these Terms, including, but not limited to any claim that all or any part of these Terms are void or voidable, or whether a claim is subject to arbitration. The arbitrator shall be empowered to grant whatever relief would be available in a court under law or in equity. The arbitrator’s award shall be written, and binding on the parties and may be entered as a judgment in any court of competent jurisdiction.\n\nThe parties understand that, absent this mandatory provision, they would have the right to sue in court and have a jury trial. They further understand that, in some instances, the costs of arbitration could exceed the costs of litigation and the right to discovery may be more limited in arbitration than in court.\n\n### 13.3 Location ###\n\nBinding arbitration shall take place in New York. You agree to submit to the personal jurisdiction of any federal or state court in New York County, New York, in order to compel arbitration, to stay proceedings pending arbitration, or to confirm, modify, vacate or enter judgment on the award entered by the arbitrator.\n\n### 13.4 Class Action Waiver ###\n\nThe parties further agree that any arbitration shall be conducted in their individual capacities only and not as a class action or other representative action, and the parties expressly waive their right to file a class action or seek relief on a class basis. YOU AND METAMASK AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING. If any court or arbitrator determines that the class action waiver set forth in this paragraph is void or unenforceable for any reason or that an arbitration can proceed on a class basis, then the arbitration provision set forth above shall be deemed null and void in its entirety and the parties shall be deemed to have not agreed to arbitrate disputes.\n\n### 13.5 Exception - Litigation of Intellectual Property and Small Claims Court Claims ###\n\nNotwithstanding the parties' decision to resolve all disputes through arbitration, either party may bring an action in state or federal court to protect its intellectual property rights (\"intellectual property rights\" means patents, copyrights, moral rights, trademarks, and trade secrets, but not privacy or publicity rights). Either party may also seek relief in a small claims court for disputes or claims within the scope of that court’s jurisdiction.\n\n### 13.6 30-Day Right to Opt Out ###\n\nYou have the right to opt-out and not be bound by the arbitration and class action waiver provisions set forth above by sending written notice of your decision to opt-out to the following address: MetaMask ℅ ConsenSys, 49 Bogart Street, Brooklyn NY 11206 and via email at legal-opt@metamask.io.

If you opt-out of these arbitration provisions, MetaMask also will not be bound by them.\n\n### 13.7 Changes to This Section ###\n\nMetaMask will provide 60-days’ notice of any changes to this section. Changes will become effective on the 60th day, and will apply prospectively only to any claims arising after the 60th day.\n\nFor any dispute not subject to arbitration you and MetaMask agree to submit to the personal and exclusive jurisdiction of and venue in the federal and state courts located in New York, New York. You further agree to accept service of process by mail, and hereby waive any and all jurisdictional and venue defenses otherwise available.\n\nThe Terms and the relationship between you and MetaMask shall be governed by the laws of the State of New York without regard to conflict of law provisions.\n\n## 14. General Information ##\n\n### 14.1 Entire Agreement ###\n\nThese Terms (and any additional terms, rules and conditions of participation that MetaMask may post on the Service) constitute the entire agreement between you and MetaMask with respect to the Service and supersedes any prior agreements, oral or written, between you and MetaMask. In the event of a conflict between these Terms and the additional terms, rules and conditions of participation, the latter will prevail over the Terms to the extent of the conflict.\n\n### 14.2 Waiver and Severability of Terms ###\n\nThe failure of MetaMask to exercise or enforce any right or provision of the Terms shall not constitute a waiver of such right or provision. If any provision of the Terms is found by an arbitrator or court of competent jurisdiction to be invalid, the parties nevertheless agree that the arbitrator or court should endeavor to give effect to the parties' intentions as reflected in the provision, and the other provisions of the Terms remain in full force and effect.\n\n### 14.3 Statute of Limitations ###\n\nYou agree that regardless of any statute or law to the contrary, any claim or cause of action arising out of or related to the use of the Service or the Terms must be filed within one (1) year after such claim or cause of action arose or be forever barred.\n\n### 14.4 Section Titles ###\n\nThe section titles in the Terms are for convenience only and have no legal or contractual effect.\n\n### 14.5 Communications ###\n\nUsers with questions, complaints or claims with respect to the Service may contact us using the relevant contact information set forth above and at communications@metamask.io.\n\n## 15 Related Links ##\n\n**[Terms of Use](https://metamask.io/terms.html)**\n\n**[Privacy](https://metamask.io/privacy.html)**\n\n**[Attributions](https://metamask.io/attributions.html)**\n\n","id":0},{"read":false,"date":"Mon May 08 2017","title":"Privacy Notice","body":"MetaMask is beta software. \n\nWhen you log in to MetaMask, your current account is visible to every new site you visit.\n\nFor your privacy, for now, please sign out of MetaMask when you're done using a site.\n\n","id":2},{"read":false,"date":"Tue Nov 28 2017","title":"Seed Phrase Alert","firstVersion":"<=3.12.0","body":"Please take a moment to [back up your seed phrase again](https://support.metamask.io/kb/article/28-abbu-always-be-backed-up-how-to-make-sure-your-12-word-metamask-seed-phrase-is-backed-up).\n\nMetaMask has become aware of a previous issue where a very small number of users were shown the wrong seed phrase to back up.

The notice must be sent within 30 days of September 6, 2016 or your first use of the Service, whichever is later, otherwise you shall be bound to arbitrate disputes in accordance with the terms of those paragraphs. If you opt-out of these arbitration provisions, MetaMask also will not be bound by them.\n\n### 13.7 Changes to This Section ###\n\nMetaMask will provide 60-days’ notice of any changes to this section. Changes will become effective on the 60th day, and will apply prospectively only to any claims arising after the 60th day.\n\nFor any dispute not subject to arbitration you and MetaMask agree to submit to the personal and exclusive jurisdiction of and venue in the federal and state courts located in New York, New York. You further agree to accept service of process by mail, and hereby waive any and all jurisdictional and venue defenses otherwise available.\n\nThe Terms and the relationship between you and MetaMask shall be governed by the laws of the State of New York without regard to conflict of law provisions.\n\n## 14. General Information ##\n\n### 14.1 Entire Agreement ###\n\nThese Terms (and any additional terms, rules and conditions of participation that MetaMask may post on the Service) constitute the entire agreement between you and MetaMask with respect to the Service and supersedes any prior agreements, oral or written, between you and MetaMask. In the event of a conflict between these Terms and the additional terms, rules and conditions of participation, the latter will prevail over the Terms to the extent of the conflict.\n\n### 14.2 Waiver and Severability of Terms ###\n\nThe failure of MetaMask to exercise or enforce any right or provision of the Terms shall not constitute a waiver of such right or provision. If any provision of the Terms is found by an arbitrator or court of competent jurisdiction to be invalid, the parties nevertheless agree that the arbitrator or court should endeavor to give effect to the parties' intentions as reflected in the provision, and the other provisions of the Terms remain in full force and effect.\n\n### 14.3 Statute of Limitations ###\n\nYou agree that regardless of any statute or law to the contrary, any claim or cause of action arising out of or related to the use of the Service or the Terms must be filed within one (1) year after such claim or cause of action arose or be forever barred.\n\n### 14.4 Section Titles ###\n\nThe section titles in the Terms are for convenience only and have no legal or contractual effect.\n\n### 14.5 Communications ###\n\nUsers with questions, complaints or claims with respect to the Service may contact us using the relevant contact information set forth above and at communications@metamask.io.\n\n## 15 Related Links ##\n\n**[Terms of Use](https://metamask.io/terms.html)**\n\n**[Privacy](https://metamask.io/privacy.html)**\n\n**[Attributions](https://metamask.io/attributions.html)**\n\n","id":0},{"read":false,"date":"Mon May 08 2017","title":"Privacy Notice","body":"MetaMask is beta software. \n\nWhen you log in to MetaMask, your current account's address is visible to every new site you visit.
