Who is Invarians for today?
Substrate context for agents protecting protocols and executing institutional flows.
Institutional RWA settlement at production scale requires multi-party attestation and decentralized verification. That trust model arrives with the hybrid Chainlink Functions DON deployment (Q3-Q4 2026) and the decentralized network (2027). Until then, the Phase 01 centralized pipeline is appropriate as a complementary structural signal in risk dashboards, not as a settlement gate.

Nominal Windows
What is nominal is not fixed. It evolves with the load.
As AI agents act on-chain at scale, their collective behavior modifies blockchain demand patterns, block saturation, transaction profiles, bridge posting cadence. The infrastructure baseline shifts. What was nominal yesterday may not be nominal today.
Invarians measures these shifts continuously and communicates the current nominal window, not as a static threshold, but as a live reading calibrated against each chain's own evolving distribution. The agent knows when the system is most nominal. The decision is its own.

The Logical Pipeline
1
Finalized on-chain data
Public blockchain data only. No mempool. No price feeds. No prediction.
→
2
Two measurement layers
Structural layer and demand layer, independently measured on each chain and each rollup.
→
3
State classification
Signed regime grid: 4 base codes (S1D1, S1D2, S2D1, S2D2) extended with direction suffixes (+, -, ±) on chains with calibrated lower bounds since 2026-04-29.
→
4
On-Chain Execution Context
Cross-layer infrastructure context, certified, signed, timestamped.
→
5
Agent Policy
The agent applies its own policy. The Pattern Reference maps each L1 · L2 · bridge combination to documented historical events.
Coverage
Three infrastructure layers. Independently measured.
L1, Ethereum · Polygon · Solana · Avalanche
Structural regime (τ) and demand pressure (π). 4 base states per chain (S1D1, S1D2, S2D1, S2D2) extended to 12 signed states on chains with calibrated lower bounds (since 2026-04-29).
L2, Arbitrum · Base · Optimism
Rollup execution profile, throughput, transaction composition, blob saturation. Distinct framework from L1.
Bridge, L2 to L1 batch posting
Batch posting continuity measured from finalized L1 data. BS1 nominal · BS2 posting gap detected. Invisible to fee monitors post-EIP-4844.
Three Primitives
Three factual outputs. The agent owns the policy.
Since EIP-4844 (March 2024), L2 sequencer incidents and bridge posting gaps produce no economic signature on L1. Fee monitors are structurally blind to what happens below the surface. Invarians measures it directly, from finalized, public on-chain data.

Attestation
The cryptographic envelope. HMAC-SHA256 over the canonical JSON payload, with key identifier and on-chain anchor slot reserved (May 2026). Independently verifiable via

02
Regime + Bridge State
The substrate and bridge state classification. 12 codes on L1 and 9 on L2 via the structural × demand grid, with signed direction extension (S2+, S2-, D2+, D2-, D2±) on chains with calibrated lower bounds (L2 demand is single-dimensional and omits the D2± variants). Bridge state (BS1 nominal / BS2 degraded) on canonical routes (CCTP V2, CCIP) classifies the bridge pipeline.

Pattern Reference (the historical frequency of each L1 × L2 × bridge combination) is a complementary research output, exposed via /patterns. It is an analytical reference, not part of the live signed payload.
