V1 Save runs on Base, where the curated-vault ecosystem is deep and clean. The venues that make institutional yield compelling, tokenized Treasuries, staked synthetic dollars, and the largest savings wrappers, are Ethereum-native, and several of them do not exist on Base in a form Tythe can integrate. This roadmap item adds them.

​
What it adds

  • Ethereum venues on the allowlist: tokenized-Treasury products, staked synthetic-dollar vaults, and Ethereum savings wrappers, each verified live before listing, with the same signals, flags, and caps as Base venues. Several require handling Tythe’s Base adapter does not: asynchronous redemption with cooldowns, conversion legs between stablecoins, and eligibility gating for products restricted to qualified purchasers.
  • An Ethereum deployment of the entity account and the venue rail, so a principal can hold an account on each chain.
  • Cross-chain value movement between a principal’s own accounts using a native stablecoin burn-and-mint rail, so capital can move to the chain where the yield is. No wrapped assets, no third-party bridge custody.

​
The rule that does not change

Credit stays on one chain. Every Loan, its lien, its capture, and its default handling live on the chain where it was originated and settle atomically there. A loss waterfall never sends a cross-chain message and never trusts a claim about another chain’s state. Cross-chain value movement is a rail for capital; it is never in the credit path. That rule is a lesson from the failures of protocols that trusted cross-chain messages in their liquidation logic, and it is not negotiable.

​
What must be true first

  • Base V1 live and audited.
  • Demand from Phase 1 principals for Ethereum-native yield.
  • The Ethereum venue adapters built and verified live, including cooldown handling and eligibility gating.
  • The Ethereum deployment audited.
