Meme coins stole alt season.
While you all wait for markets to recover back to ATH.
You will drink the hopium koolaid.
You will double down and dca your bags and be sold on.
You will either sell the bottom or hold for the next 3 years.
Wallets know where to send money, but not where to send messages.
I’ve been experimenting with an on-chain Message Routing Record (MRR) for Solana – 1 PDA per wallet with inbox key + relay URIs, no messages stored on-chain.
MRR Devnet Explorer (connect wallet, airdrop 1 SOL, init demo MRR):

Unaudited / experimental – wallets & messaging teams, would love your feedback.
#Solana
MRR for Solana is live.
Clone → build → init/read your Message Routing Record on devnet.

Screenshot: running example-init.ts prints the MRR record for your wallet on devnet.
For anyone curious on the infra side: I’m treating MRR as a simple routing primitive (not an inbox, not guaranteed delivery), so it should be easy for wallets to expose as a “publish messaging profile” toggle.

Introducing MRR: Message Routing Record for Solana
a tiny on-chain primitive that fixes the biggest missing piece in wallet-to-wallet messaging.
Every wallet should be able to say one simple thing:
“If you want to DM me, encrypt to this key and deliver to this relay.”
So I built it.
MRR is a neutral, lightweight registry that stores a wallet’s messaging profile:
🔑 Encryption public key
🌐 Primary + backup relay URIs
🏷️ Optional handle
🏁 Capability flags
🔄 Key rotation
🚫 Zero messages stored on-chain
Everything else — encryption, inbox UI, spam defenses, relays — happens off-chain where it belongs.
MRR is just the anchor point the entire ecosystem can agree on.
Today the Anchor program + TypeScript SDK are live on devnet, fully open-source.

The on-chain data is tiny and stable:
enc_pubkey (32 bytes)
primary_relay_uri
backup_relay_uri
handle
capabilities
bump
That’s it.
Everything else happens off-chain — fast, cheap, flexible.
