Bastion Review 2026: Stablecoin APIs for Businesses

Bastion is a business-facing stablecoin platform. It offers white-label issuance, custodial wallet services, crypto transfers, and fiat on- and off-ramps through APIs and dashboards. The platform is aimed at institutions and companies integrating stablecoins into their own products, rather than individuals seeking a standalone wallet.

Bastion says it handles parts of the operational stack, including reserve and liquidity management for issuance, compliance monitoring, custody, and payment processing. Businesses retain responsibility for their customer experience and distribution. Issuance APIs and dashboards are not publicly available, and companies must contact Bastion to pursue access.

The platform documentation describes sandbox access and workflows for onboarding individuals and businesses, funding stablecoin accounts, sending crypto, minting, and redeeming. Base and Solana are named as examples for wallet provisioning, but businesses should confirm the full supported chain and asset list during onboarding.

Bastion is infrastructure for businesses that want to offer stablecoin services under their own product or brand. For issuance, its APIs support fiat conversion, minting, redemption, wallet whitelisting, and supply tracking. Bastion says it manages reserves, liquidity, and compliance monitoring, while the business focuses on distribution and its customer experience.

Its custody APIs let a business create user accounts and wallets, initiate crypto transfers, and retrieve balances and transaction histories. Bastion says wallets are custodial and backed by hardware security, with transactions signed on-demand in AWS Nitro Enclaves. Optional gas sponsorship can remove the need for users to hold a network's native token for supported transactions.

Separate on- and off-ramp APIs connect stablecoin balances with fiat deposits and bank withdrawals. Businesses integrate these workflows into their own services, using Bastion's APIs, dashboards, and webhooks to manage activity and check transaction status.

Bastion does not publish fees or commercial terms in its platform overview. Pricing may depend on the business and services used; ask Bastion during onboarding for any issuance, custody, transfer, and conversion charges.

Bastion describes wallets as custodial and says wallet keys are backed by secure hardware, with transactions signed on-demand in AWS Nitro Enclaves. This reduces the need for a business to manage private keys directly, but it also creates reliance on Bastion's custody and operational controls. Stablecoin reserves, redemptions, banking relationships, and transaction monitoring carry counterparty and operational risks.

An independent audit is not identified in Bastion's platform overview. The documentation includes security topics such as key management and network security, but businesses should request details on independent assessments, incident history, recovery procedures, reserve arrangements, and applicable regulatory coverage before production use. Bastion also lists KYC and KYB onboarding requirements; specific obligations and geographic availability should be confirmed directly.

Bastion is for institutions and businesses building stablecoin features into their own apps, payment services, or financial products. It may suit teams that value outsourced custody, issuance operations, and fiat conversion, but it is not designed as a public self-service product for individual users.
