Added

Add Canton calls and offer responses (beta)

Products: Canton (Beta)

Scope: API + SDKs

• What's new
  Adds beta endpoints to submit a Canton call from a vault account's Canton wallet and to answer incoming Canton offers such as transfers, allocations, and onboarding requests.

• Impact
  Customers can now submit Canton calls and respond to incoming Canton offers through the API; this is a non-breaking addition and existing integrations are unaffected.

Affected endpoints:

1. Make a Canton call
2. Answer an offer

Add public key to proof of address result

Products: Travel Rule

Scope: API + SDKs

• What's new
  The proof of address result now includes an optional publicKey for the vault key that produced the signature, returned once the proof is signed or completed.

• Impact
  Customers can retrieve the public key required by Travel Rule counterparties for SUI, TON and XTZ, and existing integrations continue to work unchanged.

Affected endpoints:

1. Retrieve Trust Network Proof of Address Signature

Add address option to proof of address

Products: Travel Rule

Scope: API + SDKs

• What's new
  A new optional address field lets you create a proof of address for a non-default derived address on a vault account, supported for UTXO assets only.

• Impact
  Customers can prove ownership of a specific Bitcoin address instead of only the default vault address, and existing requests continue to work unchanged.

Affected endpoints:

1. Create Trust Network Proof of Address

Changed

Document mTLS CSR endpoint permissions

Products: Webhooks V2

Scope: API + SDKs

• What's new
  The webhook mTLS certificate signing request endpoint now documents that it is available only to the Owner, Admin, and Non-Signing Admin roles, matching the other mTLS configuration endpoints.

• Impact
  Workspace members without one of these roles will not be able to retrieve the mTLS certificate signing request.

Affected endpoints:

1. Get mTLS CSR
