Concrete use case, Institutional RWA cross-chain settlement
Tokenized funds are issued on Ethereum, where the deepest tokenized-asset infrastructure
has been established (multiple tokenized money market funds, on-chain credit protocols, asset-backed
instruments, totalling tens of billions of dollars in tokenized value).
Secondary liquidity and settlement increasingly move to Solana for throughput and cost reasons,
bridged via Chainlink CCIP (live on Solana since May 2025, v1.6, first non-EVM deployment).
AI agent frameworks such as ElizaOS already use CCIP for autonomous cross-chain interactions.
This creates a coordination problem between two AI agents operating on two different chains.
Agent A · Ethereum
Manages KYC / investor eligibility registry.
Verifies whitelist before any transfer.
Holds the compliance authority.
Verifies whitelist before any transfer.
Holds the compliance authority.
Agent B · Solana
Manages liquidity and settlement on Solana.
Executes transfers only on certified instruction.
Cannot act without Agent A's verified context.

Settlement flow
01
Investor requests partial redemption.
02
Agent A verifies eligibility on ETH, KYC, whitelist.
03
Agent A initiates transfer via Chainlink CCIP to Solana.
04
Before acting, Agent A queries Invarians:
ETH : SxDx ? SOL : SxDx ? CCIP ETH↔SOL : BSx ?
ETH : SxDx ? SOL : SxDx ? CCIP ETH↔SOL : BSx ?
05
Certified composite context passed to Agent B via A2A protocol.
06
Agent B verifies context via independent Invarians query.
07
Agent B executes settlement on Solana.
08
Certified execution context recorded:
"Settlement executed under certified nominal context"
"Settlement executed under certified nominal context"

Why Invarians is critical here
In institutional RWA, a settlement that fails mid-way is not a bug —
it creates an audit trail gap and a fiduciary execution failure. The institution must demonstrate that:
- The action was initiated under certified nominal infrastructure conditions
- Any deferral was justified by a verifiable infrastructure state
- The audit trail is independently reproducible
No fee monitor provides this. Invarians does.
CCIP's Risk Management Network (RMN) can pause a lane in seconds, invisible to any fee monitor. Invarians detects RMN lane status as a direct BS2 trigger, before the agent acts.
Agent A cannot instruct Agent B to execute a cross-chain settlement without knowing that both infrastructures are in a nominal structural regime. That certified handshake is what Invarians provides.
