Pay Protocol vs Sablier Lockup: Payments or Vesting? (2026)

Pay Protocol and Sablier Lockup both use smart contracts to handle tokens, but they solve different problems. Pay Protocol is a business payment and wallet-as-a-service platform. It supports collections, payouts, settlements and treasury operations, with API integration for businesses that want to connect crypto payments to existing systems. Its keyless wallet model is intended to avoid provider custody of private keys.

Sablier Lockup is a focused tool for token vesting and airdrops. Teams can set schedules with cliffs, monthly unlocks, timelocks or custom curves, create streams in bulk, and launch instant or vested airdrops. Recipients can track streams and withdraw vested funds themselves. Choose based on the workflow you need: Pay Protocol for payment operations, Sablier Lockup for planned token distribution.

Pay Protocol does not publish a fee schedule. Businesses need to check with the team for pricing on its API, wallet infrastructure or partnership program. The project claims that its fund-sweeping approach can cut gas costs by up to 95%, but that figure is a project claim without a published benchmark. Normal network gas still applies.

Sablier describes plan options and fee splits on its pricing page, but specific amounts are not published here. Users should also budget for network gas, which varies with the chain and activity. Sablier describes batch distributions as gas-efficient, but that does not establish a fixed cost. Neither service offers enough published pricing detail for a reliable fee comparison; check the current terms and likely transaction volume before choosing.

Pay Protocol says its wallets are non-custodial and keyless, which reduces the risk of a service holding client private keys. But smart-contract bugs remain a technical risk, and the security of admin permissions and multisignature settings matters. Pay Protocol has no audits listed, and its homepage names no auditor. Businesses considering it for significant funds should request audit reports and review the code and permission model.

Sablier lists two audits, and the project also cites an audit contest and other auditors. It says its contracts are audited and unchangeable, and its code is public. Audits can reduce risk but cannot eliminate it; using more chains also increases the exposure to consider. Sablier streams are designed to be unchangeable, so incorrect parameters can be hard to fix. Neither protocol is risk-free, and teams should check contract details and their own operational controls.

Pay Protocol lists Tron, BNB Chain and Ethereum. Its project describes broader multi-asset and multi-network support, but those figures are self-reported. Its keyless smart-contract model is limited to EVM-compatible environments, which is worth checking if you plan to use a non-EVM network. The product is aimed at businesses, not individual payment users.

Sablier lists 28 chains, including Ethereum, Polygon, Arbitrum, BNB Chain and Solana, and says it is live on 24+ EVM chains. Its app can be used from a wallet or opened in Safe for multisig teams. The broader deployment list may help teams working across networks, but confirm that the specific chain and token you need are supported. TVL is about $1.64 million for Pay Protocol and $1.87 million for Sablier Lockup; those figures do not measure the value of payment flows or vesting streams either product can handle.

Choose Pay Protocol if you run a business that needs to collect crypto, automate payouts or settlements, or manage treasury workflows through smart-contract wallets. API integration and system-wide multisignature settings are relevant to that use case. Its missing published fee schedule and lack of listed audits are important reasons to ask detailed questions before deployment.

Choose Sablier Lockup if your task is distributing tokens over time, managing grants or payroll vesting, or running an airdrop. Its schedule options, bulk stream creation and recipient self-service are more directly suited to those needs, and it has more published audit information. Be comfortable with streams that are designed to be unchangeable, and check the plan pricing and chain support first. These products are not substitutes: selecting the one built for your actual workflow is more useful than comparing them as general-purpose payment apps.
