Blockchains are separate networks that cannot natively talk to each other. Moving value between them — say from Ethereum to Arbitrum — currently requires trusting a third party to relay the message. That third party is the attack surface. Over $2 billion has been stolen from cross-chain bridges because of it. Someone compromised the trusted middleman and the money was gone.
Paxiom removes the middleman entirely. Instead of asking a third party "did this transaction happen on the other chain?", Paxiom generates a mathematical proof that it happened. The proof is verifiable by anyone, requires no trust, and is stored permanently so it cannot be altered or deleted.
Think of it like the difference between a bank telling you your balance and being able to count the money yourself. One requires trust. The other requires math. Paxiom is the math version.
The practical application is cross-chain finance — moving capital between blockchain networks to capture price differences, execute loans, and settle transactions without exposing users to the risk of a trusted intermediary being compromised. The same infrastructure also produces a permanent audit trail of every transaction, which is directly useful for regulatory compliance — not because someone agreed to keep records, but because the system is architecturally incapable of losing them.
Anyone who moves value between blockchain networks has a trust problem today. Paxiom solves it for three groups in particular.
Price differences exist between the same asset on different networks. Capturing them requires executing trades on two chains simultaneously. Today this requires either pre-positioned capital on both chains or trusting a bridge to move funds in time. Paxiom coordinates execution across chains without a trusted intermediary, making these trades faster, cheaper, and safer. Live scanner data shows consistent daily opportunities averaging 0.06% spread across Arbitrum, Optimism, and Base — with peaks above 0.7% during volatile periods.
Any protocol that currently uses an oracle, relayer, or validator set to verify cross-chain state can use Paxiom instead. The verification is mathematical rather than institutional — no keys to compromise, no validators to bribe, no multisig to manipulate. This is particularly relevant for lending protocols, bridges, and any application that needs to know the confirmed state of another chain before taking action.
Banks, asset managers, and funds tokenizing real-world assets need cryptographic guarantees rather than trust assumptions. They also need audit trails that satisfy regulators without depending on institutional cooperation to produce them. Paxiom provides both — mathematical verification of cross-chain state and a permanent tamper-evident record of every transaction stored on decentralized infrastructure that no party can alter or delete. Compliance by architecture rather than policy.
Paxiom is a cross-chain execution and verification infrastructure protocol. The core problem it solves is trust — every existing cross-chain protocol relies on a trusted intermediary at some point in its verification stack. Relayers, validator sets, multisig committees, and oracle networks all introduce a single point of trust and therefore a single point of failure.
Paxiom eliminates this by combining zero-knowledge proofs of Ethereum consensus state, permanent autonomous compute processes, and cross-chain messaging into a stack where no single party can halt, censor, or corrupt the verification layer.
Continuous monitoring of 13 liquidity pools across Arbitrum, Optimism, and Base. Detects structural pricing inefficiencies with velocity tracking — distinguishing capturable opportunities from noise. Over 2,400 opportunities logged with spread, direction, and persistence data.
A fully autonomous execution pipeline running on AO — a permissionless compute environment on Arweave. The opportunity monitor process evaluates every detected spread, applies cooldown and threshold logic, and fires execution signals without any human intervention. Connected to 9 geographically distributed Arweave gateways for resilience. Every signal is permanently logged to the compliance process.
When the AO monitor fires an execution signal, both legs of the trade are constructed and broadcast simultaneously — 3ms timing gap between chain A and chain B measured in simulation. This eliminates the slippage risk that makes sequential cross-chain execution impractical. Both transactions land in the same block window on their respective chains.
Unified cross-chain liquidity pool deployed on Optimism Sepolia. Accepts USDC deposits from liquidity providers, issues loans against 10% collateral, coordinates execution notification to peer chains via LayerZero, and distributes fees — 70% to LPs, 30% to protocol. First full loan cycle completed March 18, 2026 — loan issued, repaid within timeout, protocol fee collected and distributed.
LayerZero OApp contracts deployed on Optimism Sepolia and Base Sepolia. Cross-chain opportunity messages sent and received on-chain — confirmed delivery March 18, 2026. Coordinates execution across chains without a trusted intermediary routing messages.
Solidity contract integrating Aave V3 flash loans, Uniswap V3, and Aerodrome on Base. Fork-tested against live Base mainnet state. Demonstrates full execution mechanics — borrow, swap, repay — before capital deployment.
Every contract deployment, cross-chain message, loan cycle, and execution signal is logged permanently to an AO process on Arweave. No party including the protocol developers can alter or delete this record. Accessible to anyone. Compliance by architecture rather than policy.

Mainnet OApp and PaxiomPool deployment on Arbitrum and Base is the immediate next milestone. The autonomous execution pipeline transitions from simulation to live testnet broadcasts, then mainnet once timing and execution are proven end to end.
PaxiomPool v2 adds ZK checkpoint proof verification for repayment — replacing LayerZero validator trust with mathematical proof of cross-chain execution state.
The long-term trust model is a recursive zero-knowledge proof of the entire Ethereum consensus history from genesis to current head, stored permanently on Arweave. No checkpoint authority. No validator set. Mathematical verification of every Ethereum block since genesis. No cross-chain protocol has achieved this. Paxiom is architecting toward it as a concrete funded milestone.
No checkpoints. No consensus trust assumptions. Verifiable from genesis.
