Networks & Tokens

Supported networks and tokens

Network code	Chain	Tokens
`POLYGON`	Polygon PoS	`USDT`, `USDC`
`ETHEREUM`	Ethereum mainnet	`USDT`, `USDC`, `ETH`
`SOLANA`	Solana mainnet-beta	`USDC`, `SOL`

Private chains and custom payment tokens

Beyond the public chains above, ParaSta also supports payments on permissioned/private chains and merchant-issued payment tokens — useful when settlement runs entirely on your own chain without public-network crypto. Chain endpoints, token contracts, and confirmation thresholds are configured per integration; contact your representative for onboarding details.

Confirmation thresholds (finality)

Network	Confirmations before `payment.succeeded`
`POLYGON`	64 blocks (~2 min)
`ETHEREUM`	12 blocks (~3 min)
`SOLANA`	32 slots (~13 sec)

Lower thresholds are available on request for low-risk merchants.

Programmatic access

Fetch the live list at runtime:

GET /v1/networks

Use this for client UIs that need to render the picker dynamically — never hardcode the list.
