What are confidential corporate payments onchain?

Confidential corporate payments let companies settle and invoice onchain without making transaction amounts public. With the Zama Protocol, amounts, balances, and commercial references are encrypted at the token level with Fully Homomorphic Encryption (FHE), while settlement stays onchain and fully auditable. Sender and receiver addresses remain public.

Which corporate payment flows does the Zama Protocol support?

Four flows, one rail: cross-border vendor settlement, marketplace and platform payouts, treasury and intercompany flows, and trade and supply-chain finance. In each case, the commercial terms behind the transaction, such as supplier pricing, take rates, or FX strategy, stay encrypted instead of being readable by anyone with a block explorer.

How is payment data encrypted?

Vendor payments and balances are encrypted client-side, in the corporate AP system, PSP, or treasury platform, before they reach the chain. The blockchain then processes settlement, FX, intercompany flows, and reporting on encrypted data, without decrypting any of it. Data is encrypted before it leaves the institution's environment.

Which stablecoins and chains can be used?

The Zama Protocol is in production on Ethereum mainnet, asset-agnostic and chain-agnostic. It is ready to be implemented with USDC, EURC, and regulated bank stablecoins, and integrates with the custody, treasury, and ERP stack institutions already run, with no new chain to adopt. GSR and Zama completed the first confidential OTC trade on Ethereum with it.

Move corporate money onchain. Keep the terms private.

Q: Can auditors and compliance providers still access the data?

Yes. Through the Zama Protocol's Access Control List (ACL) and selective disclosure, the company decides who sees what, role by role. Auditors, sanctions-screening providers, beneficial-ownership systems, ERP, and treasury workstations retain authorized access, so the compliance stack already in place keeps running.

Corporate payments are moving onchain, but the public ledger publishes vendor terms, supplier relationships, and treasury patterns line by line.

The corporate flows that can't be public.

Cross-border vendor settlement, marketplace payouts, treasury and intercompany flows, trade and supply-chain finance, four flows, one rail.

Cross-border vendor settlement

Paying international vendors onchain makes every amount permanently visible to anyone with a block explorer. Settle in minutes without turning your supplier relationships into public data.

Marketplace and platform payouts

Merchant earnings, take rates, and fee structures are readable by every competitor on the chain. Pay out at scale without publishing your commercial model.

Treasury and intercompany flows

FX strategy, rebalancing cadence, and intercompany pricing are observable in real time by anyone watching the ledger. Move treasury onchain without giving the market a live view of your balance sheet.

Trade and supply-chain finance

Onchain invoicing exposes supplier contract values and factor pricing line by line. Finance multi-tier supply chains onchain without revealing the commercial terms behind each transaction.

Zama is a protocol, not a chain.
A standard, not a silo

The Zama Protocol is in production on Ethereum mainnet, asset-agnostic and chain-agnostic, ready to be implemented with USDC, EURC, regulated bank stablecoins, and the custody, treasury, and ERP stack institutions already run.

Client-side Fully Homomorphic Encryption

Vendor payments and balances are encrypted in the corporate AP system, PSP, or treasury platform before they reach the chain. Plaintext never leaves the institution's environment.

Computation on encrypted data

The blockchain processes settlement, FX, intercompany, and reporting without decrypting any of it. Sender and receiver addresses remain public; amounts, balances, and commercial references stay encrypted.

Compliance, control and public verifiability

You decide who sees what, role by role — through the Zama Protocol's ACL and selective disclosure. Auditors, sanctions-screening providers, beneficial-ownership systems, ERP, and treasury workstations retain authorized access; the compliance stack you already run keeps running.
