Integrates @bitgo/wasm-dot into sdk-coin-dot for WASM-based transaction parsing using Rust/subxt, replacing the JS txwrapper-polkadot path for tdot (testnet) signed transactions. ## what changed - **wasmParser.ts**: new module with `explainDotTransaction()` and `toJsonFromWasm()` that parse DOT extrinsics via WASM and map to BitGoJS TransactionExplanation / TxData formats. handles transfers, staking (bond, unbond, withdraw, chill, payout), proxy (add/remove), batch (nested + atomic), and transferAll. - **transaction.ts toJson()**: signed tdot transactions now use the WASM path (`toJsonFromWasm`), which handles metadata-aware signed extension parsing (e.g. Westend's AuthorizeCall, StorageWeightReclaim). unsigned transactions still use the legacy txwrapper path. - **webpack config**: added ESM alias for @bitgo/wasm-dot so browser builds use the fetch-based WASM loader instead of fs.readFileSync. - **tests**: 72+ new test lines in dot.ts covering WASM explain for transfers and staking. 511-line byte comparison test suite validating WASM builder output matches legacy txwrapper output byte-for-byte across all transaction types (transfer, stake, unstake, withdraw, chill, proxy, batch). - **withdrawUnstakedBuilder test fix**: numSlashingSpans assertion updated from string to number to match actual type. ## scope WASM path is only active for tdot signed transactions, gated by `this._coinConfig.name === 'tdot' && this._signedTransaction`. mainnet dot remains on the legacy path until validation is complete.

Integrates @bitgo/wasm-dot into sdk-coin-dot for WASM-based transaction
parsing using Rust/subxt, replacing the JS txwrapper-polkadot path for
tdot (testnet) signed transactions.
what changed
wasmParser.ts: new module with
explainDotTransaction()andtoJsonFromWasm()that parse DOT extrinsics via WASM and map toBitGoJS TransactionExplanation / TxData formats. handles transfers,
staking (bond, unbond, withdraw, chill, payout), proxy (add/remove),
batch (nested + atomic), and transferAll.
transaction.ts toJson(): signed tdot transactions now use the WASM
path (
toJsonFromWasm), which handles metadata-aware signed extensionparsing (e.g. Westend's AuthorizeCall, StorageWeightReclaim). unsigned
transactions still use the legacy txwrapper path.
webpack config: added ESM alias for @bitgo/wasm-dot so browser
builds use the fetch-based WASM loader instead of fs.readFileSync.
tests: 72+ new test lines in dot.ts covering WASM explain for
transfers and staking. 511-line byte comparison test suite validating
WASM builder output matches legacy txwrapper output byte-for-byte
across all transaction types (transfer, stake, unstake, withdraw,
chill, proxy, batch).
withdrawUnstakedBuilder test fix: numSlashingSpans assertion
updated from string to number to match actual type.
scope
WASM path is only active for tdot signed transactions, gated by
this._coinConfig.name === 'tdot' && this._signedTransaction. mainnetdot remains on the legacy path until validation is complete.
