Biconomy

Biconomy is the onchain orchestration layer for multi-chain applications, founded in 2019 and headquartered in Singapore. Its Modular Execution Environment (MEE) composes multi-step, cross-chain blockchain workflows — swaps, bridges, DeFi vault deposits, arbitrary contract calls — into a single user signature across 20+ EVM mainnets, handling sequencing, runtime parameter injection, bridge timing, gas abstraction, simulation-based async execution and failure recovery on the developer's behalf. The commercial surface is a REST Supertransaction API (POST /v1/quote, POST /v1/execute) plus the TypeScript AbstractJS SDK, both sitting on the same engine and the same project API key. Underneath, Biconomy ships open-source account-abstraction infrastructure: an ERC-4337 bundler, ERC-4337 paymasters for gas sponsorship and pay-in-token flows, and Nexus, an ERC-7579 modular smart account audited by Cyfrin, Spearbit, Zenith and Pashov. Smart Sessions layers scoped, time-limited, revocable on-chain delegation on top, which is how AI agents and automations transact on a user's behalf without holding their key. Biconomy also authored ERC-8211 for composable batching.

Biconomy publishes 3 APIs on the APIs.io network: instructions API, mee API, and root API. Tagged areas include Account Abstraction, Blockchain, Bundler, Cross-Chain, and DeFi.

The Biconomy catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Biconomy’s developer surface includes authentication, developer portal, documentation, engineering blog, support, sandbox, changelog, and 71 more developer resources.

scored 2026-09-08 · rubric v0.20.0
Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/biconomy: open an issue to ask a question, or submit a pull request to add artifacts.

  modular smart account audited by Cyfrin, Spearbit, Zenith and Pashov. Smart Sessions layers scoped, time-limited, revocable
