aptos

Complete pure-Dart rewrite aligned with @aptos-labs/ts-sdk v7.2.0:
namespaced Aptos facade, full account/key support (incl. keyless with
client-side Groth16 verification and encrypted transactions), wire-exact BCS,
and pure-Dart BN254 + BLS12-381 pairings. pana 160/160.

Complete, ground-up rewrite with a new namespaced architecture.

• Breaking: the legacy AptosClient / CoinClient / TokenClient / FaucetClient / IndexerClient / AptosAccount API has been removed. See the README's migration table.
• Breaking: the package is now pure Dart — the Flutter dependency was removed (usable in server-side Dart, CLIs, and Flutter alike).
• New Aptos facade + AptosConfig with namespaces: account, coin, general, transaction (build/simulate/submit/batch), faucet, table, fungibleAsset, digitalAsset (Token v2), staking, object, ans, keyless, abstraction.
• New account hierarchy: Account.generate(), Ed25519 (legacy), AIP-55 SingleKey (ed25519/secp256k1), secp256r1/WebAuthn keys, MultiKey, MultiEd25519, Keyless & FederatedKeyless (OIDC/ZK, pure-Dart poseidon), account abstraction (AA/DAA), EphemeralKeyPair.
• Full transaction pipeline: remote-ABI argument encoding, multi-agent and sponsored (fee payer) transactions, orderless transactions (replayProtectionNonce), simulation, batch submission worker, pluggable TransactionSubmitter.
• Keyless: full local signature verification, including the BN254 Groth16 proof check (pure-Dart pairing), plus network-backed verifySignatureAsync (fetches the keyless configuration and JWKs from chain).
• Encrypted transactions: batch-encryption payloads via a pure-Dart BLS12-381 pairing implementation (BIBE identity-based encryption, RFC 9380 hash-to-curve, AES-128-GCM), wired into the build flow through options.encrypted.
• BCS layer and all curve/pairing primitives validated byte-for-byte against the official SDK and independently generated reference vectors; 700+ unit tests.

• Fix dio Transformer type

• Fix bcs simulate

• Add query pending tokens
• Add AnsClient

• Add typeTag and multiSig

• Add optInTokenTransfer and multiSig

• Initial version, created by 0xmovebuilder.
