Adds a NativeWalletTokenBalances bus member so a host can read the wallet's catalogued token balances. Today that is the Solana cluster's USDC mint (devnet or mainnet, chosen from the existing catalog by the configured cluster).
web3: WalletEngine::token_balances() reads getTokenAccountsByOwner(owner, {mint}, {encoding: jsonParsed}) through the host transport and sums tokenAmount.amount over every token account the owner holds. No accounts reads as zero. A provider failure, or an answer that names another mint, gives a zero row marked missing instead of failing the read (same convention as native balances).
module: serves the member; manifest method lists updated.
Native balances stay in NativeWalletBalances, so existing consumers (the OpenHuman wallet panel keys rows by chain/network) are unaffected.
Why
An autonomous OpenHuman agent needs to check its USDC balance before paying bounties and vendors. The host must not run chain reads itself (its web3 README: no host-side wallet algorithms), so the read lives here.
Host adapter: tinyhumansai/openhuman PR to follow (linked below once open). OpenHuman can consume this only after a tinywallet release and re-pin, because the host contract minor rises to 1.15.
Added access to catalogued token balances for configured wallets, including Solana SPL tokens. Results include token details, formatted amounts, and provider status; balances are summed across matching token accounts.
Updated the wallet contract to version 1.15 to support token balance queries.
…es (contract 1.15)
Add a NativeWalletTokenBalances member returning TokenBalanceInfo rows for
the catalogued tokens of each configured account. Today that is the Solana
cluster's USDC mint (devnet or mainnet from the catalog), read with
getTokenAccountsByOwner (jsonParsed) and summed over every token account the
owner holds. A provider failure, or an answer for another mint, yields a zero
row marked missing rather than failing the read. Native balances stay in
NativeWalletBalances so existing consumers keep one row per network.

Full summary
Pull request purpose (title): feat: NativeWalletTokenBalances — SPL token (USDC) balances, contract 1.15. Adds a `NativeWalletTokenBalances` bus member (contract 1.15) so a host can read catalogued token balances — today the Solana cluster's USDC SPL mint — as `TokenBalanceInfo` rows kept separate from native `BalanceInfo` rows. The web3 engine reads `getTokenAccountsByOwner` with `jsonParsed`, sums `tokenAmount.amount` across the owner's token accounts, treats no accounts as zero, and falls back to a zero row marked `missing` on provider failure or a foreign-mint answer. The module serves the member and manifest method lists are updated. The tests lane answered and flagged one gap: the documented refusal of an unparsable amount in `sum_parsed_token_amounts` has no test that would fail if dropped. The latest-push delta is unavailable.

Completeness: Incomplete Test assessment: Test coverage is assessed from changed tests and lane evidence; execution is not claimed without trusted check data.
What changed
Contract version rises to 1.15 with a new `NativeWalletTokenBalances` method and a `TokenBalanceInfo` wire row (camelCase, `evmNetwork` omitted when unset). The web3 engine gains `token_balances()` and a Solana `token_balance`/`sum_parsed_token_amounts` read path.
Features
Added — NativeWalletTokenBalances bus member and contract 1.15: Hosts gain a new dispatch member for catalogued token balances; the contract minor bump means hosts must re-pin to consume it. (crates/tinywallet-bus/src/names/mod.rspub mod methods {, crates/tinywallet-bus/src/names/mod.rspub const METHODS: &[&str] = &[, crates/tinywallet-bus/src/version/mod.rs)
Added — TokenBalanceInfo wire row: Token balances are reported as their own row type with mint address, decimals, raw and formatted amounts, and provider status, kept apart from native BalanceInfo rows so existing consumers keep one row per network. (crates/tinywallet-bus/src/wire/wallet.rspub struct BalanceInfo {, crates/tinywallet-bus/src/wire/mod.rspub use wallet::{)
Added — WalletEngine::token_balances read path: Reads each catalogued Solana mint for each configured Solana account via getTokenAccountsByOwner/jsonParsed, summing token accounts; provider failure or a foreign-mint answer yields a zero row marked missing rather than failing the read, and an unconfigured wallet returns the not-configured error. (crates/tinywallet-web3/src/crypto/execution/queries.rsimpl WalletEngine {, crates/tinywallet-web3/src/crypto/chains/solana/mod.rspub(crate) async fn native_balance(engine: &WalletEngine, address: &str) -> Resu, crates/tinywallet-web3/src/crypto/execution/types.rsuse crate::quote::Quoted;, crates/tinywallet-web3/src/crypto/execution/mod.rspub(crate) use types::PreparedTransferQuote;)
Added — Module service wiring for the new member: The module serves the member through the active native service handle, requiring a valid handle and mapping engine errors to native-wallet operation failures; the manifest method list includes it. (crates/tinywallet-module/src/service/mod.rsimpl Wallet {, crates/tinywallet-module/src/service/mod.rsmod exports {)
Tests
unit — token_balances sums every SPL account of the catalog USDC mint, asserts the RPC method and params, uses the devnet mint on devnet with no accounts reading as zero, marks unreadable or foreign-mint answers missing, and errors when the wallet is unconfigured.: Covers the happy path, cluster-dependent mint selection, foreign-mint refusal and provider-failure fallback. The tests lane notes the documented refusal of an unparsable amount in sum_parsed_token_amounts has no test that would fail if it were dropped, so a malformed provider amount could regress to a silent zero.

tests
Conclusion: Success
Scope reviewed: all assigned evidence
Positive: Tests lane answered: new tests cover the happy path, cluster-dependent mint selection, foreign-mint refusal and provider-failure fallback, but the unparsable-amount refusal in sum_parsed_token_amounts lacks a test that would fail if dropped.
Lane summary: The change adds the `NativeWalletTokenBalances` contract member with a `TokenBalanceInfo` wire row and Solana SPL balance reads, and the new tests cover the happy path, cluster-dependent mint selection, the foreign-mint refusal and the provider-failure fallback. One stated refusal in the new `sum_parsed_token_amounts` doc comment — refusing an unparsable amount — has no test that would fail if it were dropped, so a malformed provider amount could regress to a silent zero without anything catching it.

description
Conclusion: Success
Scope reviewed: all assigned evidence
Positive: Description lane answered: the description matches the diff, naming the new bus member, wire type, contract bump to 1.15, the web3 read path with its zero/missing fallback, the module wiring and the added tests.
Lane summary: The description matches the diff: it names the new bus member, wire type, contract bump to 1.15, the web3 read path with its zero/missing fallback, the module wiring, and the tests that were added. I found no description defect.
The change adds a Contract 1.15 method for catalogued token balances. The web3 engine queries Solana token accounts and returns token rows with balance and provider status. The native-wallet module exposes the query through its service.
The bus contract advances to version 1.15. It adds TokenBalanceInfo and NativeWalletTokenBalances to the public type and method declarations. Contract tests and documentation describe the new method and row format.
WalletEngine::token_balances reads catalogued Solana mints for configured accounts. The Solana query sums parsed amounts for matching mints. Tests cover summed, empty, failed, mismatched-mint, and unconfigured-wallet cases.
Module service integration crates/tinywallet-module/src/service/mod.rs, crates/tinywallet-module/src/service/web3_native_wallet_tests.rs, crates/tinywallet-module/tests/*
The module service exposes the engine query and adds the method to its advertised list. Service and end-to-end tests include the method and check a Devnet USDC balance row.
The token-balance feature has a small documentation inconsistency. Correct the operation count; no material runtime failure is established by the supplied evidence.

Place the Contract 1.15 paragraph in version order.
The paragraph sits between the Contract 1.5 and Contract 1.7 paragraphs. The README is not strictly ordered (1.2 and 1.12 appear later), so this is only a readability point. Move it after the Contract 1.12 paragraph so the newest contract is easy to find.
