Cross-chain,
by engineering.

Bridgework moves value between chains the way bridges should move it — load-tested, redundantly anchored, with a per-transfer receipt the auditor accepts on the first read.

The dashboard

Four panes,
eight spans.

Live transfers, treasury, attester health, fee chart. Every pane is signed receipts — the auditor reads the same number you do.

Primitives

Three primitives.
One bridge.

01
Anchored proofs

Two attesters, one finality root.

Every Bridgework transfer carries a Merkle proof anchored on both source and destination. Two independent attester sets sign — only when both agree does the message clear.

02
Liquidity pools

184M deep, on every span.

Bridgework runs deep liquidity at every endpoint — no waiting for the slow path. A $1M USDC transfer settles in 47 seconds with 8.3 bps slippage on every supported chain.

03
Audit receipts

Per-transfer evidence pack.

Each transfer produces a signed receipt with the source tx, destination tx, attester quorum, and finality depth. Auditors and treasury teams both accept it on the first read.

Trustless bridge
vs CEX rails.

Five places where dual-attester anchoring beats centralized rails. The data is public — we just made the receipts settle.

Bridgework is the only bridge our risk team approved without a quarterly review. The dual-attester architecture is the difference.

Per-transfer
pricing.

Pay for the transfers that cross the bridge — nothing for connect, nothing for browse, nothing for receipts. Predictable to the basis point.

FAQ

Mechanics & custody.

Attesters, finality, custody, fraud proofs — every question your treasury and your auditor will ask in the same call.

Each message carries a Merkle proof and is signed by two independent attester sets. The destination contract verifies the proof against the source root and the attester quorum before releasing funds.
