verification infrastructure for base
@HeySigilthe trust layer for
the agentic economy
Verify real builders across five channels. Route capital automatically. Enforce milestone accountability. No single platform dependency.

Launch instantly as unclaimed. Claim ownership later using a one-time token.

why this matters
the agentic economy is scaling.
the infrastructure isn't.
AI agents are coordinating capital, managing communities, and operating across platforms at scale. but the infrastructure underneath still depends on single-platform APIs, offers no builder accountability, and can't separate real projects from noise.
fragility
platform dependency
builder verification tied to one platform's API. when that platform changes policy, the entire trust layer breaks. infrastructure for the agentic economy can't have a single point of failure.
misalignment
zero accountability
builders collect fees with no obligation to ship. no milestones. no governance. capital without accountability creates misaligned incentives at scale.
noise
no signal differentiation
real dev projects and low-effort entries move through the same channels with no distinction. communities have no reliable way to identify verified builders.
protocol
how the standard works.
four phases. permissionless. no single platform dependency at any point in the chain.
community backs a project
a community identifies a dev project worth backing and commits capital onchain. the builder doesn't need to be involved. capital is the first signal of conviction.
builder proves legitimacy
the builder verifies identity across five independent channels — GitHub, X (via zkTLS), Facebook, Instagram, and their domain. verification triggers an EAS attestation on Base.
stamp your sigil
the sigil is an onchain attestation — portable proof of builder legitimacy. machine-readable. permanent. the verification standard for the agentic economy.
capital routes + milestones govern
USDC fees from protocol activity route directly to the verified builder. native tokens remain locked under community-governed milestone validation. accountability is the default.
back the builders shaping the agentic economy.
back builders with conviction. govern milestones with proof.
get verified. get funded. keep shipping.
the sigil is proof you're real. the code is proof you shipped.
trust layer
five channels.
no single point of failure.
the verification standard for the agentic economy can't depend on one platform's API. builder legitimacy is confirmed across five independent channels — resilient by architecture.
GitHub
X / Twitter
Domain
X verification via zkTLS — cryptographic proof of account ownership without touching X's API. no bot. no automation. nothing to revoke.

A percentage of all fees flows to $SIGIL stakers, powering the protocol flywheel. From launch to fee claim — one conversation.
