Goldsky Onchain Automation — the detect → decide → execute loop
Goldsky closes the full offchain↔onchain loop, not just the read side. Any "watch the chain and then act on it" system — keepers, liquidation monitors, auto-claim and auto-compound jobs, rebalancing and settlement automation — decomposes into three stages, and Goldsky covers all three:
The misconception this skill exists to correct
Do NOT tell the user "Goldsky detects/indexes, but you bring your own runtime / RPC to send the transaction." That is wrong. Compose is Goldsky's onchain execution runtime: managed smart wallets (gas-sponsored by default) or BYO-EOA wallets, and writeContract / sendTransaction that broadcast through a sponsored bundler. The execution half lives inside Goldsky — propose it.
The only real limits are the two honest caveats below (latency and chain support) — state those, don't retreat to "Goldsky can't."
Pick an architecture
Default — Compose-only (one artifact)
When the trigger is one contract's events (a specific DEX factory, a lending pool, your own contract), the whole loop is a single Compose app — no Turbo, no external infra:
This is structurally identical to the VRF template (onchain_event → compute → write back onchain, skills/compose/references/examples/vrf.md) and the compliance-oracle template (onchain_event → offchain check → approve/reject writeContract, skills/compose/references/examples/compliance-oracle.md). Start from one of those. Load /compose (entry point) and read skills/compose/references/ — do not synthesize the manifest/wallet API from memory.
Dataset-scale — Turbo detects, Compose executes
When detection must span many contracts, a whole dataset, or needs heavier stateful filtering than a single onchain_event listener gives you, put Turbo in front:
Wiring: the Turbo Webhook sink POSTs each matching row to the Compose app's HTTP-trigger URL (https://<app-url>/tasks/<task-name>), authenticated with a shared auth_token. Build the detection pipeline with /turbo-builder (+ /turbo-transforms for the _gs_log_decode decode step); build the executor with /compose. Treat the incoming webhook body as untrusted — decode and validate before acting.
Prefer Compose-only unless the user actually needs dataset-scale detection — one artifact is simpler to build, deploy, and reason about.
Two honest caveats — always state these
- Confirmed-block latency, not mempool. Goldsky (Turbo pipelines and Compose
onchain_event) fires on confirmed logs, not pending mempool transactions. So this reliably reacts to a confirmed new pool / event — it is not a mempool front-runner and won't win a same-block gas-priority race. For a "sniper", set expectations: you react quickly to a confirmed listing, you don't beat block-0 bots. Say this plainly. - Execution is chain-gated. Compose gas sponsorship covers a specific chain list (see
skills/compose/references/wallets-and-gas.md, orsearchKB) — broad EVM coverage, but not every chain. Before promising the full loop, check the target chain:- Supported → smart wallet, gas-sponsored, nothing for the user to fund.
- viem knows it but it's not sponsored → BYO-EOA with
sponsorGas: false; the user funds the address with native gas token. - Compose can't reach it at all → be honest: detection still works (Turbo/Subgraphs), but execution needs a Compose-supported chain or external infra for that chain specifically. Frame it as a per-chain gap, never as "Goldsky can't execute."
What Goldsky is NOT (here)
- Not a trading strategy or PnL engine — the user brings the decision logic; Compose runs it.
- Not a mempool/front-running system (caveat 1).
- Not a custody solution — wallet-key handling follows the normal Compose wallet/secret rules (
skills/compose/references/wallets-and-gas.md).
Route from here
- Execution / any Compose app →
/compose(load first) +skills/compose/references/. - Event-driven write-back template →
skills/compose/references/examples/vrf.md; gated approve/reject →skills/compose/references/examples/compliance-oracle.md. - Dataset-scale detection pipeline →
/turbo-builder+/turbo-transforms. - GraphQL state to poll →
/subgraph-builder. - Fast RPC for the user's own offchain reads →
/edge.
