Intro

Meta Transactions let users sign intents for voucher actions without paying gas. A relayer/queue submits the signed intent on-chain, and Euclid verifies the signature before executing the action. This makes cross-chain voucher operations fast and user-friendly, while keeping verification on-chain.

For a deeper overview, see Meta Transactions concepts.

Supported Actions​

  • Swap using voucher balances
  • Transfer voucher balances
  • Withdraw voucher balances

Chain Notes (Cosmos vs EVM)​

Meta transaction payloads share the same structure across Cosmos and EVM. The primary differences are the values you provide (e.g., chain_uid, addresses, and token identifiers). If chain-specific rules apply to fields like forwarding_message, they will be documented here.
