Changelog

• Mainnet is running an updated validator build that adds on-chain support for secure account migration.
• Some early accounts from the 2019–2022 period relied on weak keys. Once this was identified, those accounts were protectively frozen on the chain to keep their balances safe.
• This update introduces a governed migration path that moves such an account's balances and holdings to a new, securely generated address.
• The first migration batch has now been applied on mainnet, and further batches will follow.
• Consensus reliability was also improved: validators gained a leadership standby path for faster and smoother leader failover.

• The developer GitBook now documents Phantasma Link v5, including the pairing flow, transports, sessions, and the script transaction format.
• RPC API key support is documented, covering per-key rate-limit tiers and how to send an API key.
• SDK documentation was updated to current package versions, with regenerated API references across the SDKs.
• Fee guidance was expanded, including C++ Carbon fee defaults and per-type max-gas calculation for integrators.
• Network economy and block production pages were added and cross-linked, and the quick-start onboarding pages were reworked with copyable endpoint tables and clearer entry pages.

Developer documentation

• Devnet and testnet RPC now support API keys that grant higher rate-limit tiers: node operators can issue keys for higher-volume access, and can optionally run a node in keys-only mode.
• All seven Phantasma SDKs can now attach an API key to the RPC client, so requests use the matching rate-limit tier on nodes that issue keys.
• The same RPC build returns NFT lookups that find nothing as a clean not-found result instead of surfacing as an error.
• Controlled API errors now propagate with their intended status and message instead of being flattened by a catch-all handler.
• Updated SDK packages: phantasma-sdk-ts 0.11.0 (TypeScript), phantasma-sdk-py 2.2.0 (Python), phantasma-sdk 1.2.0 (Rust), phantasma-sdk-go v0.11.0 (Go), and PhantasmaPhoenix.RPC 0.8.0 (.NET), plus updated C++ and Unity SDKs.

• Phantasma Link v5, the new dApp-to-wallet connection protocol, is now stable (specification v1.0), and the v5 client is available in the TypeScript SDK (phantasma-sdk-ts 0.10.1).
• One structured message envelope (a JSON-RPC 2.0 profile) replaces the old string protocol and works across every transport, so requests are typed, independent, and can run concurrently.
• A capability handshake lets the dApp and wallet agree up front on supported methods, chains, transaction formats, payload sizes, and features, instead of guessing from a version number.
• Every session is end-to-end encrypted with NaCl and is a real, revocable session; relays only ever see ciphertext.
• The same envelope runs over several transports: the Ecto browser extension, a desktop loopback channel (now bound to localhost only), a mobile deeplink path, and a self-hosted relay for large payloads and cross-device pairing.
• Mobile and iOS are first-class: the deeplink path needs no wallet-hosted local server and keeps working even when the relay is down.
• The old ~32 KB request limit is gone. Transactions can now carry up to the chain's real ceiling of 1 MiB of metadata and 32 MiB per transaction.
• Existing v1–v4 dApps keep working. Phantasma Link v5 is purely the connection layer and changes nothing on the chain, validators, or RPC.

Phantasma Link v5 specification | phantasma-sdk-ts on npm

• React bindings for Phantasma Link v5 are published as phantasma-link-react (renamed from @phantasma/connect-react). Wrap your app once, drop in a connect button, and call the typed pha_* methods through a small reactive store over the v5 client.
• A public relay is live at link.phantasma.info. It is an end-to-end-blind WebSocket pub/sub server that carries large transactions, cross-device sessions, and wallet events while never seeing their content.
• A playground is live at link-test.phantasma.info. It runs the same operations side by side over Phantasma Link v5 and the legacy v4, so you can compare them and try the cross-device relay (QR) and same-device deeplink flows.
