feat: add wbtc.eth, usdt.sol, usdt.arb on chainflip, fix usdc.arb and eth.arb (#3050)
What changed, and why it matters
This commit adds support for new cryptocurrencies (wrapped Bitcoin on Ethereum, Tether on Solana and Arbitrum) and fixes mapping labels for USD Coin and Ethereum on Arbitrum within the Chainflip exchange integration. It is a routine feature/configuration update with no apparent security relevance.
No security action required; review as normal feature code.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff updates two Dart files: (1) cw_core/lib/crypto_currency.dart adds USDC and USDT on Arbitrum to the exchangeCurrencies list, defines new CryptoCurrency constants (usdcArb, usdtArb), and renumbers the raw ID for ltcmweb to avoid a collision with the previous 107 value now used by zec/usdtArb; (2) lib/exchange/provider/chainflip_exchange_provider.dart adds WBTC, USDT-SOL, USDT-ARB to the supported currency list, adds an ‘ARBITRUM’ network-name mapping, and adds parser cases for wbtc.eth, eth.arb, usdc.arb, and usdt.arb. No cryptographic, authentication, or input-validation logic is changed.
