Seismic Systems

Seismic Systems Inc. is a fintech company building a privacy-enabled ("encrypted") blockchain — a shielded EVM implementing the "Mercury" specification — that aims to power a complete stablecoin stack. Backed by a $17M seed led by a16z crypto, Seismic lets developers build private tokens (SRC20) whose balances and transfers are hidden from observers, using shielded types in Solidity, TEE-encrypted calldata (ECDH + AES-GCM), and authenticated "signed reads." It ships first-party client SDKs for TypeScript (seismic-viem, seismic-react), Python (seismic-web3), and Rust (seismic-alloy), an sfoundry developer toolchain (sforge/sanvil/ssolc), a public testnet with a faucet and block explorer, published Claude Code agent skills, and a read-only SRC20 Factory REST API for querying deployed tokens.

Seismic Systems publishes 1 API contract indexed on the APIs.io network: Tokens API. Tagged areas include Company, Blockchain, Privacy, Encryption, and Stablecoins.

The Seismic Systems catalog on APIs.io includes 1 Spectral governance ruleset.

Seismic Systems’ developer surface includes documentation, API reference, getting-started guide, support, CLI, sandbox, authentication, and 15 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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 does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks

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.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Stablecoins and Tokenization (stablecoin issuers, tokenized assets)	mixed	44.1	-	-
IDE Extension Marketplaces (JetBrains, VS Code, Open VSX, Docker Verified Publishers, PyPI orgs)	mixed	44.1	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
