A ton of this is just completely untrue.
1) Kelp originally used the defaults which were MultiDVN or DeadDVN and manually migrated to a 1/1 config later
2) Almost 100% of the volume on a 1/1 config was rsETH
3) Not using a 1/1 for production applications is mentioned many times in the documentation.
The defaults Kelp is referencing in their screenshot were multiDVN or DeadDVN, which force-rejects an application using the defaults at all and requires them to manually set configuration.
rsETH was originally configured to use the default LayerZero configuration of a multiDVN setup of LayerZero Labs Google:
Here are the exact transactions where that happens
Ethereum → Arbitrum:
etherscan.io/tx/0xd7c864adbc…
at 2024-02-06 03:09:47 UTC
Ethereum → Optimism:
etherscan.io/tx/0x7075bfe9a3…
at 2024-02-06 03:09:59 UTC
KelpDAO then manually changed these to 1/1 configs:
For the original Feb 6 Ethereum routes to Arbitrum/Optimism, KelpDAO’s Ethereum contract switched from defaults to manual OApp-scoped config on 2024-04-01:
Send-side manual config:
etherscan.io/tx/0x7485c16c9b…
2024-04-01 07:12:11 UTC
Receive-side manual config:
etherscan.io/tx/0x21e967c99a…
2024-04-01 07:12:23 UTC
From this point on, Kelp began deploying all of their configurations as 1/1 configs. Here is Kelp’s deployment on Unichain:
Unichain → Ethereum was opened on 2025-04-01 18:55:41 UTC.
Pathway-open / setPeer tx:
uniscan.xyz/tx/0x31ea2b10a73…
The manual ULN config followed 6 seconds later in
uniscan.xyz/tx/0xd8ef5416a53….
During this time the Unichain -> Ethereum and Ethereum -> Unichain defaults were set to DeadDVN which is a contract which makes it impossible for any application to transact without manually configuring their DVNs, this was not possible on the defaults of this pathway.
Here is the code in the DeadDVN (
etherscan.io/address/0x747C7…) that specifically prohibits this.

This is called out many many times in the docs:

- Content: "Do not assume defaults are safe for production. Always check explicitly: getSendLibrary, getReceiveLibrary, and getConfig. If these resolve to defaults, confirm whether the defaults are valid for the intended pathway. Unintentional fallbacks to defaults are a common cause of blocked or failing pathways."

▎ Should I use multiple DVNs?
▎ Recommended for production. Multiple DVNs provide:
▎ - Increased security (multiple independent verifiers)
▎ - Resilience (no single point of failure)
▎ - Trust minimization

Here are the exact recommendations we gave KelpDAO when asked about DVNs (typically 2/3)

For how much volume was actually configured on 1/1 here is the exact data.
