Wallet & Crypto Operations
(heart of the Agent OS for DeFi; foundation for truly Autonomous Decentralized Finance)
5.1 Account Lifecycle & Custody Modes
Self-custody
Ephemeral in-process key + encrypted local vault or HSM
Power users, small teams
Key never leaves host; hot-key rotation APIs; can step-up to hardware signing.
MPC / Threshold
Sharded between engine node(s) and cloud HSM
Institutions, DAOs
No single point of compromise; supports geo-redundant quorum signing.
Smart-wallet (AA)
Contract-based account with programmable auth (EIP-4337, ERC-6900)
Mass retail, gas-sponsored UX
Meta-tx relay, pay gas in stablecoins; social recovery baked in.
Custodial (Delegated)
Coinbase Prime, Fireblocks, or in-house custodian
Regulated desks
Degents signs typed payloads → custodian cosigns & broadcasts; policy engine remains authoritative.
Lifecycle primitives
create_account() · import_account() · rotate_keys() ·export_view_key() · destroy_account()
All emit signed attestations stored in Layer 4 for audit & recovery.
5.2 Multi-Chain & Rollup Coverage
EVM
Ethereum L1, Base, Arbitrum, Optimism, Polygon PoS, zkSync, Scroll, Starknet, Linea
Shared ethers-rs core; deterministic nonce manager across networks.
Solana
Mainnet, Devnet
ed25519 signing; compute-budget auto-estimator.
Cosmos / IBC
Osmosis, Neutron, Injective
CosmJS adapter; IBC intents route via Bridge Router.
BTC-style UTXO
Lightning (via LND gRPC), Liquid
PSBT builder; taproot key-path spend support.
Move-VM
Sui, Aptos
BCS encoder; forecasted for phase 2 roll-out.
Chain support is declarative: add a ChainAdapter manifest and Degents auto-generates RPC, Tx-Builder, and Gas-Oracle bindings.
5.3 Built-in “Action” Catalogue
Native Asset
native.get_balance, native.transfer
Pay-as-you-go or sponsor via AA.
Tokens
token.transfer, token.approve, token.deploy (ERC-20/SPL/CW-20)
Batched approvals to minimise gas.
DEX & Liquidity
dex.swap, dex.add_liquidity, dex.remove_liquidity (aggregates Uniswap v3, 0x, Pancake, Jupiter)
Path-finder auto-quotes; bundle flashes via mev-protect RPC.
Lending / Yield
lending.supply, lending.borrow, lending.repay, lending.withdraw (Aave v3, Morpho Blue, Spark)
Health-factor sim before sign; auto-repay on liquidation risk.
Derivatives
perp.open_position, perp.close, perp.add_margin (GMX, dYdX chain)
Sub-second oracle stamping; twap check guard.
NFT
nft.mint, nft.transfer, nft.list
Royalties resolved on-chain; optional seaport listing.
Bridging
bridge.xchain_transfer
Slippage-capped intents; proofs logged for fallback.
Fiat Rails
fiat.on_ramp, fiat.off_ramp
Compliant identity token required; KYC proof enforced via Policy Engine.
All actions implement the Intent-Simulation-Signature trilogy:
graph LR
Intent -->|simulate()| PolicyCheck -->|sign()| TxBuilder -->|submit()| Chain
Receipts funnel back to the Memory Kernel, triggering learning or human notifications.
5.4 Gas & Fee Management
Gas Oracle Mesh — medianised data from on-chain feeds + off-chain mempool observers; p95 deviation < 2 gwei (EVM)
Sponsorship / Paymaster — AA smart wallets allow agents (or sponsors) to pay gas in USDC, DAI, or native; Policy Engine enforces daily gas budget.
Bundle & Multicall — Tx Builder auto-batches compatible calls; saves 18–32 % gas in benchmark tests.
MEV protection — Flashbots & EdenRogue lanes; private tx routes for high-value intents.
Dynamic Fee Token Routing — If agent lacks native gas, Degents auto-swaps micro-amount of stables → native token in a single atomic bundle.
5.5 Illustrative End-to-End Flow
Human voice prompt: “Rebalance treasury to 60 % stables, 40 % ETH across chains, cap gas at $200.”
Intent Draft — Rebalance-agent decomposes task into
dex.swap(AVAX→USDC),bridge.xchain_transfer(USDC to Base), pluslending.repay(Aave).Policy Check — KYC token verified, gas-cap constraint validated (
≤ $200).Simulation — Cross-chain path runs in forked sandbox; VaR < policy threshold.
Signing & Batching — Tx Builder assembles three cross-chain bundles, each meta-tx sponsored in USDC.
On-chain Execution — Receipts confirm; gas actually spent: $176.42.
State Update — Treasury allocation now 60/40; Memory Kernel logs performance; dashboard notifies CFO.
The same pipeline handles an arbitrage bot, payroll stream, or DAO vote execution—illustrating how Degents makes sophisticated, policy-safe crypto operations one Intent away, realising the promise of an autonomous decentralized finance platform.
