The permissioned-token standard behind most institutional RWA issuance, maintained by the ERC-3643 Association. With Bubble underneath, eligibility stays enforced while positions and transfers stop being public signals.
How the integration works
Bubble sits between the application and the chain. ERC-3643 keeps doing what it does today, and confidentiality is added at the token layer: amounts and balances live on chain as ciphertexts, computation happens across the MPC network without decryption, and disclosure is governed by the contract rather than by us. Contracts stay standard EVM, so nothing has to be rewritten.
Private by design.
