While AA clients can make Solana/Tron/Stellar/etc sign requests, these transactions are not gas subsidized. This is because AA clients on Solana/Tron/Stellar/etc utilize a standard MPC wallet under the hood, which doesn’t support gas sponsorship in the same way as EVM-based chains.

For Solana networks, account abstraction is supported through the use of the
feePayer
field in transactions.If you set a policy for a mainnet chain, your account will be charged for gas subsidization even if you are on your Portal Development environment. Please set policies for Testnet chains while you are still building or testing to avoid unnecessary charges.
Generating smart contract wallets for your users
Generating smart contract wallets for your users is incredibly easy with Portal.Step 1: Get access to the feature
Reach out to the Portal team to request access.Step 2: Create Clients with Account Abstraction
After Portal enables Account Abstraction for your organization, you are ready to create your first clients. This can be achieved by hitting the Create a new client endpoint with this as the request body:Step 3: Generate a Smart Contract Address!
Now that you have Account Abstraction enabled for your client, you can use the SDKs as you normally would to create a wallet, back it up, recover it, and sign. Since Account Abstraction is now enabled for the client, the address returned after creating a wallet is a smart contract address. With the completion of the above steps, you would have successfully created a client with Account Abstraction. Congratulations! :tada: You can now proceed to use the Portal SDKs and services as usual.The client’s smart contract wallet is only deployed upon their first successful
eth_sendTransaction
request.The hash from signing with an Account Abstraction client is a user operation hash, not a transaction hash. Use tools like Jiffy Scan to explore user operations.
Clients using Account Abstraction require dApps they interact with to support EIP-1271 for verifying signed messages.
