Changelog

These docs describe @altananetwork/sdk 0.7.1 and @altananetwork/mcp 0.7.1, the current releases on npm.

Both packages are pre-1.0. Minor versions may contain breaking changes. Pin an exact version if you need stability across installs.

The canonical file is CHANGELOG.md in the SDK repo.

0.7.1

Released 12 August 2026. @altananetwork/mcp 0.7.1.

• grantSession returns the grant's transaction hash. The result is now GrantSessionResult, a Session plus an optional transactionHash. Granting is the one call that charges the user a Keystore registration fee, twice on a wallet's first admin action, and it was the only entry point that discarded the hash instead of forwarding it. execute, revokeSession and registerSessionKey were already returning it.
• grant_session reports the transaction hash in the MCP server, alongside the session details and keyId, matching every other write tool.

Not a breaking change: GrantSessionResult is assignable everywhere a Session is expected. One thing to watch as a consumer, an explicit const session: Session = ... annotation narrows the type back down and hides the new field. Let the type be inferred, or annotate with GrantSessionResult.

0.7.0

Released 4 August 2026. @altananetwork/mcp 0.7.0.

• Skills registry discovery in the MCP server. search_skills searches the registry by name, description, and tags. get_skill fetches a skill's full playbook, integrity checked against the registry's sha256 before it is returned, so a tampered playbook is rejected rather than followed. See Skills Registry.

• B402 envelope compatibility. The x402 client and server now speak the B402 envelope dialect on both sides, fixing payments against BNB-chain sellers that expect it.

0.6.0

Released 16 July 2026. @altananetwork/mcp 0.5.0.

• ERC-8183 buyer support. Hire BNB Agent Studio seller agents from an Altana wallet: escrow, job status, and settlement as one atomic relay intent. Available in the SDK and as the erc8183_* MCP tools.
• @altananetwork/x402-server. Seller-side x402/B402 package: payment challenges, verification, and on-chain settlement.

0.5.0

Released 14 July 2026. @altananetwork/mcp 0.4.0.

• BNB testnet support (chain 97).
• Optional session-key Keystore registration. grantSession takes a register flag, on by default; registerSessionKey registers a key later.
• ERC-20 balances with BEP-677 support. Scaled-UI-amount tokens are detected via ERC-165 and their display value is scaled, leaving the raw on-chain amount untouched.

0.4.0

Released 14 July 2026. @altananetwork/mcp 0.3.0.

• x402 payments. Pay HTTP payment challenges with a session key over Permit2 or EIP-3009, including the B402 permit2-exact witness rail.
• ERC-1271 signature verification for smart-account wallets.

0.3.3

Released 8 July 2026. First public release: agentic wallets, session keys, the Keystore registry, the MCP servers, and this documentation site.

Entries for 0.6.0 and earlier were reconstructed from commit history after the fact, so they summarize what shipped rather than itemizing every change.
