Custodial Vs Non-Custodial Wrapping

Custodial wrapping involves a centralized entity that holds the underlying assets in a secure vault and issues the wrapped tokens, introducing significant counterparty risk. Users must trust the custodian to maintain the collateral and facilitate redemption, often requiring KYC and legal oversight.

In contrast, non-custodial or trustless wrapping utilizes automated smart contracts to handle the locking and minting process, removing the need for a trusted intermediary. While non-custodial methods minimize counterparty risk, they shift the burden of security to the underlying code and the decentralization of the validator set.

Both models aim to provide asset utility on foreign chains but differ fundamentally in their trust assumptions.
