Weekly Dev Update #74

This update and the next will be light as part of the team take end-of-year breaks.

Summary

The team continues prep the chain for Multichain, significant progress has been made on Ethereum support. The Router contract is here:

contracts/Router.sol · master · THORChain / Bifrost / Eth Vault Contract

Vault Contracts for Bifrost

The ROUTER simply manages allowances between vaults, whilst ETH is forwarded through the contract. This allows both ETH and ERC-20 assets to be managed by smart contract calls.The User deposits with a MEMO to the ROUTER, but gives an allowance to a desired ASGARD to spend. ASGARD can then fund Yggdrasil by transferring allowances to spend.YGG vaults can transfer out to Users, emitting an MEMO in the process.
YGG vaults can transfer all their assets back to the ASGARD (forwarding ETH and revoking allowances to spend) with a single contract call.

In addition, the team wrote a Draft SeedService, which can be reviewed by the community here:

contracts/SeedService.sol · master · THORChain / Bifrost / Eth Vault Contract

Vault Contracts for Bifrost

The SeedService is designed to be a static entrypoint into the system.
The User should be able to connect to THORChain with just this contract address and a Web3 provider.

The SeedService allows any Asgard to report a list of IPs as a string.
The SeedService expects multiple Asgards, so is append-only.

A user can query to get "last seed" or "recent seed" or seeds from a specific Asgard.
Users should not trust any Asgard, so should query multiple times.
Paranoid users can check the balance of the Asgard address to see the presence of Asgard funds.

• Ethereum: Almost complete
• Gaia: Under review
• Haven: Under implementation
• BitcoinCash: Under implementation
• Polkadot: Under implementation
