 | Access keys | Wallets, account SDKs, and apps using connected apps or subscriptions | Existing authorized access keys remain valid for delegated transaction flows. T3 adds optional periodic limits and call scoping, bans contract creation from access-key transactions, and changes the authorization ABI used to create or rotate keys. |
 | Signature verification precompile | Smart contract teams, account integrators, and wallet SDKs | Contracts can verify secp256k1, P256, and WebAuthn signatures through one precompile instead of custom verifier contracts. |
 | Virtual addresses | Exchanges, ramps, custodians, payment processors, explorers, and indexers | Partners can generate per-user TIP-20 deposit addresses that forward to a registered master wallet. Explorers and indexers should display and attribute forwarded deposits correctly. |
-| Node upgrades | Node operators, RPC providers, and infra teams | T3 also includes security hardening and gas correctness fixes. All operators should roll out the T3-compatible release before activation, even if they do not plan to use the new features directly. |
