Many reports actually have a certain reading threshold. I will briefly summarize the differences in the implementation of the technology of [account abstraction] in the three systems: $ETH /$SOL /$ATOM 🔻

1. Account abstraction under the SOL and COSMOS systems does not currently support multi-signature, but it is already achievable, but has not yet been officially deployed

2. The account abstraction wallet of the COSMOS system does not need to create a new account, while in ETH, it can only be implemented after the EIP-3074 upgrade is completed

3. Like the first point, the account abstraction schemes of the SOL and COSMOS systems cannot currently support the function of assisting in the recovery of social accounts, but it is also achievable but not deployed

4. In conclusion: the EIP 3074 proposal, which has not been officially implemented, has gone the furthest and most comprehensive in the area of ​​wallet account abstraction (implemented in 2025), followed by the currently used ERC-4337, and then COSMOS. Solana's overall progress is slower than the first two factions
