is optional. Solana defaults to a gas limit of 200,000 micro-lamport (10^-15 SOL).To transition from EVM chains to Solana, set the blockchains
parameter value to SOL
on mainnet, or SOL-DEVNET
on testnet.
When creating wallets for end-users, follow these steps to allow them to transfer assets:
For developer-controlled wallets, use existing wallet sets to generate Solana wallets and change the following body params:
EOA
SOL
or SOL-DEVNET
For user-controlled wallets, use the same X-User-Token
header parameter for the same end-user. If it expires, create a new user token. Change the following body parameters:
EOA
SOL
or SOL-DEVNET
Next, for both wallets, specify the wallet metadata associated with an end-user during or after wallet creation:
User Wallet1
UUID1
To fund Solana testnet wallets, update the following body params:
SOL-DEVNET
Set up the Gas Station policy for Solana in mainnet. Testnet environments come with pre-set default policies.
Specify the transaction detail in the following API endpoints:
Ensure the blockchains
body parameter is set to SOL
or SOL-DEVNET
Currently, the response to a POST
request to the /transactions/transfer/estimateFee
endpoint is the same for each fee level (high
, medium
, low
). This will be updated in a future release.
