Tokenized Asset Custody: Wallets and Trustees

Tokenized asset custody has evolved from simple private key storage into a complex transaction control layer that bridges blockchain-based claims with traditional legal and fiduciary frameworks. This hybrid model integrates cryptographic wallet technology with the oversight of trustees and institutional custodians to ensure compliance with securities laws and operational requirements. The article highlights that for regulated entities, self-custody is insufficient, necessitating multi-signature wallets or multi-party computation (MPC) to manage assets like tokenized treasury bills, bonds, and money market funds. Key institutional players such as Anchorage Digital, Fireblocks, and BNY are utilizing these advanced architectures to maintain segregation and auditability. The shift is critical for the RWA market because it aligns on-chain token movements with off-chain legal settlement, as seen in projects like Fidelity International’s liquidity fund on zkSync and CETES on Stellar. Ultimately, the success of tokenized assets depends on the ability of custodians to reconcile smart contract activity with fund accounting and regulatory reporting. This infrastructure is essential for institutional adoption, as it ensures that the digital token and the underlying real-world asset remain legally synchronized.
