what is the best RPC node provider + mempool service for 7702 smart accounts?

we need robust support for transaction nonce queuing to prevent failures on successive txs. we want to avoid using 4337 bundlers.

who has the best solution for this?

Great question — with 7702 smart accounts still evolving, finding a provider with strong nonce management outside the 4337 flow is tricky. Ankr and Alchemy both offer solid RPC reliability, but you might want to look into Blocknative’s mempool service for advanced transaction tracking and queuing.

For nonce queuing specifically, TURBO (by Stackup) is experimenting with solutions tailored for smart account flows — even without 4337 bundlers. Might be worth exploring or reaching out directly to see how flexible their stack is.
