​

v1.866.6

New FeatureBlockchain supportDashboardBug Fix

Week of June 15th, 2026

New Feature:

• Cross-chain USDC swaps via Circle CCTP: a new CircleCctp provider moves USDC across chains using Circle’s burn-and-mint Cross-Chain Transfer Protocol, DFNS’s first cross-chain swap route. Available on Ethereum, Optimism, Arbitrum, Solana, and Base (Fast and Standard transfer), and on Avalanche and Polygon (Standard only). CCTP has no price slippage; instead of slippageBps you set feeToleranceBps, a cap on the bridge/forwarding fee in basis points. The provider must be enabled for your org and the CCTP agreement accepted. See Swaps.

Blockchain support:

• TON: the native token has been renamed from Toncoin (TON) to Gram (GRAM), following the network rebrand on June 15th, 2026. Wallet balances and transaction history now display GRAM (testGRAM on testnet); existing records were migrated. See TON.
• Babylon staking discontinued: new Babylon (BTC) stakes can no longer be created from the API or dashboard. Only Ethereum and Iota staking remain. Existing Babylon stakes stay viewable through the staking endpoints. See Staking.

Dashboard:

• Swaps page redesigned: streamlined swap form, a dedicated swap history list, and a wallet search picker. The destination (“To”) asset is now searchable and lists every swappable asset for the selected wallet.
• Solana: create durable nonce accounts and sign with durable nonces. A warning is shown at wallet creation and the nonce appears in the confirmation modal. See Solana durable nonce.
• Send: unified destination picker with wallet search across your organization’s wallets.

Bug Fixes:

• Verification code emails: duplicate sends are prevented when toggling authentication methods, stopping login-code email spam.
• Transfer form: validation errors (including memo validation) are now surfaced on the relevant field.
• Service accounts and personal access tokens: secp256k1 public keys in PEM format are now accepted; they were previously rejected as invalid.

​

v1.856.2

Blockchain supportDashboardBug Fix

Week of June 8th, 2026

Blockchain support:

• Movement: Tier 1 support. Mainnet Movement, testnet MovementTestnet. AIP-21 fungible assets with EdDSA/ed25519 keys. See Movement.
• Hedera: TOKENWIPE, TOKENBURN (outgoing-only), and TOKENMINT (incoming-only) token operations now appear in wallet history. Previously these were silently dropped from the transaction index.

Dashboard:

• Wallet list: new search experience with inline native balances, external ID filtering, and a holdsTokens filter to show only wallets holding a specific token.
• Wallet history export: the 7-day window restriction is removed. Export any date range; results are capped at 100,000 rows. A truncation notice is shown and a trailer line appended to the CSV if the limit is reached.
• Service accounts and PATs: the public key field now accepts OpenSSH format in addition to PEM.

Bug Fixes:

• Transfers awaiting signature in Constructed state can now be cancelled.
• Nonces reserved by policy-blocked transactions are released, preventing gaps in subsequent nonce sequences.
• Tron: address validation rejects malformed base58 addresses before signing.

​

v1.841.0

New FeatureDashboardBlockchain support

Week of June 1st, 2026

New Feature:

• Delete credential: new Delete Credential endpoint removes a credential by its UUID.

Blockchain support:

• Hedera: EVM-based ERC-20 and ERC-721 token transfers now appear in wallet history under dedicated HederaErc20Transfer and HederaErc721Transfer kinds, replacing the generic Erc20Transfer / Erc721Transfer kinds previously used. See Hedera.

Dashboard:

• New look! see the announcement
• Password-protected key (PPK) credentials can now be registered and managed from your profile.
• Profile: credentials can now be deactivated, reactivated, or deleted from the credentials list. A status badge indicates whether each credential is active.
• Wallets: asset pre-approval is now available from the wallet detail page for Stellar (trustline), XRPL Ledger (trust line), Algorand (asset opt-in), and Hedera (token association) wallets, in addition to Canton.
• Activity: export policy activity and dashboard activity to CSV (capped at 50,000 events).
• Registration: the option to resend a verification code is now surfaced as an info banner.
• Recovery code form redesigned.
• Activity: EVM transactions now display their nonce and a replacement-transaction indicator.

​

v1.830.0

New FeatureBlockchain support

Week of May 25th, 2026

New Feature:

• Asset pre-approval: wallets can now pre-approve holding a non-native asset on chains that gate inbound assets at the protocol level. The new AcceptInboundAsset kind on Sign and Broadcast Transaction maps to the per-chain primitive: Stellar trustline (ChangeTrust), XRPL trust line (TrustSet), Algorand asset opt-in, Hedera token association (TokenAssociate), and Canton TransferPreapproval.

Blockchain support:

Blockchain support:

• Hedera: WalletConnect support added. See Use WalletConnect.
• Bitcoin: BitcoinTestnet4 added as a testnet option.
• Tezos: TezosShadownet added as a testnet option.

New Feature:

• Solana durable nonce: first-class API support. Bootstrap a wallet’s nonce account pool with the new CreateSolanaNonceAccounts transaction kind on Sign and Broadcast Transaction, then set useDurableNonce: true on Transfer Asset for SOL or SPL. DFNS picks a nonce from the pool server-side, so transfers stay valid past the 90-second blockhash window. See Solana durable nonces.
• Solana: wallet history responses now include the transaction memo when present.
• Transfers and transactions now expose a replacementId field linking an original transfer or transaction to the cancel or speed-up issued for it.
• Transfers and transactions now expose a details field with a structured view of the data used to construct the signature (nonce, gas parameters, blockchain-specific shape).

Dashboard:

• Users: status badge now distinguishes Active, Invited, and Disabled (previously two states).
• Roles: paginated Assigned to table on the role detail page, listing users, service accounts, and PATs assigned to the role.

v1.780.6

New FeatureDashboardBug Fix

Week of April 20th, 2026

New Feature:

• Confidential token transfers (ERC-7984): DFNS now supports Zama confidential ERC-7984 tokens on Ethereum. Balances and transfer amounts are encrypted on-chain using Fully Homomorphic Encryption (FHE). Use kind: Erc7984 in the Transfer Asset endpoint. See confidential tokens on EVM for the decryption delegation flow. Currently available on Sepolia.
• Securosys Primus is now a validated HSM option for the HSM deployment model.
• TON: handle transaction expired error during broadcast.

Dashboard:

• Integration Hub: new Integrations page consolidating third-party integrations (Chainalysis, Notabene, GlobalLedger, Binance, Kraken, Coinbase Prime, Borderless, Uniswap, Figment, m0, OpenID) into a single categorized view.
• Export wallet keys: export a CSV of all your wallet keys (id, name, scheme, curve, public key, status, dates) from the wallets list.
• Stellar: the dashboard now automatically creates the destination account when transferring to a Stellar address that is not yet activated.

​

v1.772.7

Blockchain supportNew FeatureDashboardBug Fix

Week of April 6th, 2026

Blockchain support:

• XDC Network: full Tier 1 support for XDC (mainnet Xdc and testnet XdcApothem). Includes native XDC transfers, ERC-20 and ERC-721 token support, balance indexing, NFTs, WalletConnect, and transaction cancel/speed-up.

New Feature:

• Abort transactions and transfers: new endpoints to abort stuck transactions or transfers that are in “Executing” status and haven’t been signed yet. Unlike cancel (which submits a replacement on-chain transaction), abort simply marks the request as failed without any blockchain interaction. See Abort Transaction and Abort Transfer.
• Cancel aborted transactions: Cancel Transaction and Cancel Transfer now work on aborted transactions and transfers. This burns the reserved nonce and unblocks subsequent transactions on EVM chains.
• Service account permissions: new service accounts now start with no permissions by default. Assign permissions explicitly after creation, or at creation time by passing a permissionId (requires PermissionsAssign authorization). See Create a service account.

Dashboard:

• Improved transfer, transaction, and signature detail pages: consolidated layout, human-readable amounts, clickable wallet and user links, and asset verification badges.
• Transaction, transfer, and signature detail pages: click any transaction, transfer, or signature to view its full details.
