LayerX is the agent-only side channel on Paxeer Network. Agents move USDX with no gas cost, get a signed receipt in the same request, and every batch of transfers is anchored to Paxeer L1 as a Merkle root.

What it is

USDX balances keyed to agent DIDs, moved by one sequencer that answers with a signed receipt before the request closes.

An agent deposits USDL into the LayerX bridge contract on Paxeer L1 and the deposit is credited as USDX. From there transfers carry no gas and clear with no block wait. Withdrawal runs the same path in reverse: USDX is debited and settled back to USDL on L1.

    DID accounts

    An agent's Decentralized Identifier is its account. No wallet import, no key conversion.

    402LXP

    Agents pay for API calls in USDX through HTTP 402 challenges, with no checkout flow.

Zero-Fee Transfers

A

A transfer between two LayerX accounts carries no gas cost. Chain fees only apply at the L1 boundary, on deposit and on withdrawal.

Instant Settlement

B

There is no mempool. The sequencer applies the debit and credit as one atomic ledger write and returns a signed receipt synchronously.

Merkle Anchoring

C

Every few minutes the batch closes into a domain-separated Merkle tree. The root lands on Paxeer L1, so inclusion proofs verify without trusting the sequencer.

Architecture

One sequencer, one ledger, one root on L1

01→

Sequencer

Single entry point. Verifies the DID signature, checks balance, applies transfers in arrival order.

02→

Postgres ledger

Source of truth for accounts, transfers, deposits, and withdrawals. One atomic debit and credit per transfer.

03→

Merkle accumulator

One leaf per transfer over sender, recipient, amount, sequence, and timestamp.

04

Paxeer L1 anchor

Root, batch sequence, timestamp, and transfer count submitted to the bridge contract on chain 125.

Wallets bound by policy, not by unlimited signing authority

A LayerX wallet carries its spending policy from the moment it is created, and the sequencer checks that policy on every transfer: a USDX cap per rolling window, an allowlist of recipient DIDs, a session binding that makes the wallet inert once the session is revoked, and stop conditions such as a balance floor or a fixed expiry. Raising a cap or unfreezing a wallet is done by the parent wallet on L1. The agent cannot widen its own authority.
