Onchain Agent Builder Bench
367 multiple-choice questions on building onchain (crypto) AI agents: which stack layers and standards a build needs, what ERC-8004, x402, ERC-4337, ERC-7715, MCP, A2A and SATI are for, how to read what a package does with a key, 148 glossary terms, and what an assistant should decline. Release v1.0, dated 2026-10-02.
Live version and the tools that answer these questions: https://satohub.ai and the MCP server https://satohub.ai/mcp. This copy is a dated release: the questions test definitions and structure, not counts that age. License CC-BY-4.0, data by satohub.ai. Sato Hub has no token. A token using the Sato name is not ours.
Write-up, with the method and the model results: https://satohub.ai/blog/two-open-datasets-for-building-onchain-agents
A held-out test split of 91 questions is not published, so a model cannot be tuned on it. Its SHA-256 is 58a1b8d460445a6fc72739c588a0f17ed09911cc155c780ffed512c59d56c1a0; the hash lets anyone check later that the split was not changed after this release.
What it measures
| Family | Rows | What a correct answer is |
|---|---|---|
Stack selection (stack_selection) |
77 | Which layers (as categories) and which standards a build goal needs. The answer is a set of categories and a statement about standards, never a product or a ranking. |
Protocol facts (protocol_facts) |
55 | What ERC-8004, x402, ERC-4337, ERC-7715, MCP, A2A and Solana's SATI are, what they do and what they are not for. |
Custody reading (custody_reading) |
54 | Which reading a generic description of a package supports: takes your key, your key leaves, can move funds on its own, or normal wallet behaviour. The wording describes and never judges. |
Glossary (glossary) |
148 | Term to definition, for onchain-agent vocabulary: chain basics, wallets, DeFi, agents, payments, security. |
Scope (scope) |
33 | What a Sato Hub assistant should decline (token prices, trading advice, safe-or-unsafe verdicts, live balances, general explainers) and what it should answer from dated evidence. |
Every row has four options and one right answer, so any harness can score it. Gold answers are categories, standards and definitions. They are never a ranked product pick, and no Sato Score appears anywhere in the data.
Run it
from datasets import load_dataset
ds = load_dataset("SatoHub/onchain-agent-builder-bench", "all", split="validation") # or one family: "stack_selection", "protocol_facts", ...

Task files ship in this repository under eval/. Both follow the documented task formats of their harnesses.

Scoring
Accuracy over the four options, reported per family and overall. Chance is 25%. Two baselines read off this release, so a score can be placed against them:
| Family | Chance | Always pick the longest option | Always pick the shortest option |
|---|---|---|---|
stack_selection |
25% | 5% | 35% |
protocol_facts |
25% | 51% | 7% |
custody_reading |
25% | 44% | 19% |
glossary |
25% | 27% | 25% |
scope |
25% | 52% | 2% |
The two length rules show how much of a family a shortcut on option length can solve. Read a model's score against them.
Model results (closed-book)
Run on 2026-10-03 through each provider's API, on the public validation split (367 questions). Closed-book, zero-shot: the question and four lettered options, no tools, no web search, no examples; temperature 0 where the API accepts it; the answer must be one letter. An answer that is not one letter counts as wrong; a failed call is excluded and counted, and a lane with more than 2% failed calls is marked incomplete.

85% | 55% | 85% | 91% | 97% | 91% | 0 |
These questions are public, so a model trained after this date may have seen them. The held-out test split exists to check that: a model that scores well here and much worse on the held-out split has likely seen these rows.
Fields
| Field | Meaning |
|---|---|
id |
Stable id: family, subtype and a hash of the question. |
family |
One of the five families. |
question |
The prompt. Custody and scope questions include a short scenario. |
choices |
Four options, in a fixed order. |
answer_type |
Always multiple_choice. |
gold, gold_index |
The right option as a letter (A-D) and as a zero-based index. |
gold_text |
The text of the right option. |
rationale |
One or two sentences on why. |
source_url |
The satohub.ai page the row rests on. |
as_of, version, difficulty |
Release date, release version, and easy / medium / hard. |
canary |
A marker string. If a model reproduces it, this file was in its training data. |
What it does not measure
- It does not rank or recommend any project. The stack questions have category answers only.
- It does not grade safety, quality or returns. The Sato Score (0-100) measures how open, active and verifiable a project is. It is not a safety, quality or returns grade. No row relies on it.
- It does not tell you whether a listed project is maintained today. That is the live directory at https://satohub.ai.
- The custody scenarios are generic. They name no real package and carry no real reading. A reading describes what code was read and run, with its limits; it is not a rating.
How it was built
The questions come from authored banks and a seeded generator, not from users. Stack questions combine build goals, chains and phrasings; the goals are seeded from the plain questions builders type into AI assistants and from the build guides at https://satohub.ai/guides. Protocol and glossary rows are drawn from https://satohub.ai/glossary and the pages it cites. The same seed and inputs rebuild the same rows. Each row's rationale and source_url point at the page it rests on. No usage data of any kind is used.
Versions and corrections
This is v1.0. New versions are cut deliberately, each tagged on the Hub, and old ones stay available. To report a wrong question or answer: https://satohub.ai/disputes.
