  description: The Biconomy Supertransaction API exposes the Modular Execution Environment (MEE) over a small REST surface
    — POST /v1/quote composes a multichain execution plan and returns the signable payload(s) and fee, and POST /v1/execute
    submits the signed supertransaction for cross-chain settlement. Three account modes are supported - smart-account (Nexus
    / ERC-4337), eoa (MetaMask, Rabby, Trust funded by an explicit fundingToken), and eoa-7702 (EIP-7702 set-code delegation
    for Privy / Dynamic / Turnkey embedded wallets). Composable instruction types include intent-simple, intent, intent-vault
    (200+ DeFi vaults), build, build-raw, and build-ccip.

    — full sponsorship (developer pays gas, post-paid invoiced monthly) and pay-in-tokens (user pays gas in ERC-20). All sponsorship
    limits (per-tx USD cap, per-user daily cap, allowed contracts, chain whitelist) are configured per project in the Biconomy
    Dashboard and enforced before /v1/quote returns a sponsored quote.

    policies (Sudo, Universal Action, Time Range, Usage Limit) that bound what an agent or automation can execute on behalf
    of the owner. Intended for agents, recurring automations, and intent-flow access without re-prompting the owner for every
    transaction.

    API and Nexus smart account operations, exposing createMeeClient, getQuote, executeQuote, and waitForSupertransactionReceipt
    helpers, plus composable instruction builders for cross-chain orchestration, conditional execution, runtime balance injection,
    and cleanup.
