Trustlines
On Stellar, accounts must explicitly opt in to hold and use assets. This opt-in is called a trustline.
Trustlines are how Stellar accounts opt in to issued assets.
If an account has no trustline, it cannot hold that asset.
What is a trustline?
A trustline links an account to an asset issuer.
It allows the account to receive, hold, and send that asset.
It includes a limit (max balance you accept).
It tracks balance and liabilities (like open offers).
Why trustlines matter for escrows
Trustless Work escrows can use any Stellar-issued asset.
Every participant must be able to hold that asset.
If a signer can’t hold the escrow asset, their step may fail. Set trustlines before testing any escrow flow.
Issuer addresses (USDC / EURC / USDT0)
Use these issuer addresses when you configure the escrow trustline.
