Send MsgOutboundTransfer | 1. BTC addr is funded2. Vault supply is decreased3. Int3face token supply == vault balance | TODO | | 3 | Key generation | - 3 observer nodes- 3 int3face nodes- 3 BTC nodes | Observer int3face, BTC nodes are healthy | 1. Generate gov proposal to execute KeyGen tx2. Vote on the proposal and accept it | 1. Old vault is empty2. New vault is funded3. New vault balance is decreased by the fee | TODO | | 4 | Vault migration: inbound transfer to the new vault | - Funded BTC addr- 3 observer nodes- 3 int3face nodes- 3 BTC nodes | Observer int3face, BTC nodes are healthy | 1. Generate gov proposal to execute KeyGen tx2. Vote on the proposal and accept it3. Send tokens from BTC addr to the new vault | 1. Old vault is empty2. New vault is funded (old vault + incoming tokens)3. New vault balance is decreased by the fee4. Int3face balance is funded5. Int3face token supply == vault balance (considering fees) | TODO | | 5 | Vault migration: outbound transfer from the new vault | - Funded int3face addr- 3 observer nodes- 3 int3face nodes- 3 BTC nodes | Observer int3face, BTC nodes are healthy | 1. Generate gov proposal to execute KeyGen tx2. Vote on the proposal and accept it3. Send MsgOutboundTransfer | 1. Old vault is empty2. New vault is funded (old vault - outgoing tokens)3.

Int3face token supply == vault balance (considering fees) | TODO | | 6 | Vault migration: multiple chains | - Funded int3face addr- 3 observer nodes- 3 int3face nodes- 3 BTC nodes- 3 DOGE nodes | Observer int3face, BTC, DOGE nodes are healthy | 1. Generate gov proposal to execute KeyGen tx2. Vote on the proposal and accept it3. Send MsgOutboundTransfer to BTC4. Send MsgOutboundTransfer to DOGE | 1. Old vault is empty2. New vault is funded (old vault - outgoing tokens)3. New vault balance is decreased by the fee4. BTC addr is funded5. DOGE addr is funded5. Int3face token supply == vault balance for both BTC and DOGE (considering fees) | TODO | | 7 | Observer shutdown after vault migration | - Funded int3face addr- 3 observer nodes- 3 int3face nodes- 3 BTC nodes- 3 DOGE nodes | Observer int3face, BTC, DOGE nodes are healthy | 1. Generate gov proposal to execute KeyGen tx2. Vote on the proposal and accept it3. Shutdown the observer | 1. Old vault is empty2. New vault is funded (old vault - outgoing tokens)3. New vault balance is decreased by the fee4. Pool public key is updated for all the observers5. Last observed height is updated for all the observers | TODO | ## Steps to implement[​](#steps-to-implement "Direct link to Steps to implement") 1. Find libraries to run all the nodes in docker containers (there may be some dedicated repos to run BTC and DOGE): [79](https://github.com/Int3facechain/bridge/issues/79). 2. Scaffold tests, test utilities and helpers: [80](https://github.com/Int3facechain/bridge/issues/80). 3. Test `Inbound transfer`: [81](https://github.com/Int3facechain/bridge/issues/81). 4. Test `Outbound transfer`: [82](https://github.com/Int3facechain/bridge/issues/82). 5. Test `Key generation`: [83](https://github.com/Int3facechain/bridge/issues/83). 6. Test `Vault migration: inbound transfer to the new vault`: [84](https://github.com/Int3facechain/bridge/issues/84). 7. Test `Vault migration: outbound transfer from the new vault`: [85](https://github.com/Int3facechain/bridge/issues/85). 8. Test `Vault migration: multiple chains`: [86](https://github.com/Int3facechain/bridge/issues/86). 9. Test `Observer shutdown after vault migration`: [87](https://github.com/Int3facechain/bridge/issues/87). 10. Research how to run tests in the CI/CD: [88](https://github.com/Int3facechain/bridge/issues/88).
