did you mean it should be "Reverse registrars" rather than "Registrars"? otherwise the change makes the terminology inconsistent

Fair enough. In that case it should make it clear that reverse registrars set their own custom resolver, which only allows the name to be set.

i might need to reword some of this. "Reverse registrar" = L2 contract that maintains the registrar capability, "Reverse resolver" = L1 contract that resolves to the L2 registrar values.
| - For a valid resolution, the user must also set the appropriate `addr()` record on their ENS name | ||
| - This completes the two-way verification between address and name |

I am interested in something resembling this draft acting as a fallback for the ENSIP-11 close-loop addr check. Not sure if it should be enshrined here against the ENSIP-19 spec or just added as additional functionality for ENSIP-11.

| ### Resolving an avatar by a dapp on another EVM chain | ||
| 1. Let `chainId` be the chain ID of the client. | ||
| 2. If `chainId` is an L1 chain ID (including Ethereum testnets), set `reverseName = "[address].addr.reverse"` and `coinType = 60` and go to step 5. |

Maybe: If default (chainId = 0), set reverseName = "[address].default.reverse" and coinType = 0x80000000 and go to step 5.
| 9. Set `node = namehash(name)` | ||
| 10. Fetch the forward-resolved address from the resolver: | ||
| - If `coinType == 60`, with: `resolvedAddress = ensip10.resolve(reverseName, encodeCall('addr', [node]))` | ||
| - Otherwise, with: `resolvedAddress = ensip10.resolve(reverseName, encodeCall('addr', [node, coinType]))` |

This and the prior line, reverseName should be name

I've discussed this a bit with Tate before, but should we include the forward fallback logic? or add another ENSIP after this? (I prefer including it.)
If resolvedAddress is null and chainFromCoinType(coinType) > 0, then resolvedAddress = ensip10.resolve(reverseName, encodeCall('addr', [node, 0x80000000])).
Note: chainFromCoinType() > 0 ⟺ "non-default EVM coin type"
Note: this can be accomplished with a multicall.
