Summary: SEDA is a programmable oracle-infrastructure project that lets developers define custom data-access and transformation logic as deployable “Oracle Programs.” Its official materials describe a stack in which builders choose data sources, filtering and aggregation rules, and delivery method, then deploy that logic to the SEDA network as WASM-based programs that can be consumed through onchain delivery paths or through the lower-latency SEDA Fast API/WebSocket surface. In this pass, SEDA looked less like a generic oracle brand and more like a developer control plane for bespoke oracle execution, especially for custom feeds, session-aware market data, and agent-driven workflows.
What it does:
Lets developers build Oracle Programs that define what data to fetch, which public or private sources to use, and how results should be filtered, aggregated, and returned
Stores deployed Oracle Programs on the network as WASM binaries with Oracle Program IDs, so the network can execute and relay requests rather than forcing each app to run one-off custom oracle infrastructure
Offers two main delivery surfaces: SEDA Core for permissionless onchain delivery through prover-contract flows, and SEDA Fast for lower-latency REST and WebSocket access to Oracle Program execution
Positions the system for more than simple crypto price feeds, including session-aware tradfi pricing, private-API access through Data Proxies, and programmable policy logic around data validity and fallback behavior
Publishes agent-oriented runbooks, AI-readable docs, audit references, and public code repositories for the chain, starter kits, contracts, and example Oracle Programs
Key claims:
The homepage markets SEDA as “The Internet Onchain” and says developers can access programmable oracle infrastructure in minutes, including 24/7 pricing for trad-fi assets and access to 11+ million symbols
The architecture docs say Oracle Programs let builders program their own oracle feeds for any data type, define source selection and aggregation rules, and deploy the resulting logic to the network as WASM binaries
The docs explicitly separate sourcing, oracle logic, and delivery, with SEDA Core supporting onchain delivery and SEDA Fast supporting low-latency offchain access via REST and WebSocket interfaces
The agent-oriented documentation frames SEDA as programmable oracle infrastructure for autonomous agents, with deterministic policy execution, machine-to-machine workflows, and copyable build/deploy/execute runbooks
Official audit pages and GitHub repos make the project look like a shipping production stack rather than a pure research narrative
Whitepaper: No classic standalone whitepaper or litepaper was located in this pass. The strongest primary materials were SEDA’s official site, architecture and developer docs, agent-oriented docs, audit references, and public GitHub organization; see ../whitepapers/seda-primary-sources-2026-04-25.md.
