Migration
SLR to kSLR migration guide.
SolarCoin is moving to the Base network on May 15, 2026. Here is everything you need to know about the transition — including the one action custodial holders must take before snapshot.
Which holder are you?
Jump straight to the steps for your situation.
What is changing?
On May 15, 2026, the SolarCoin team snapshotted every SLR balance on Energy Web Chain and Ethereum mainnet. Existing holders can now claim kSLR on the Base network at the same address. You have one year — until May 15, 2027 — to claim your kSLR. The economics are unchanged: 1 kSLR per kWh, just like 1 SLR per MWh before.
Legacy
Before: SLR
1 SLR per MWh of solar production on Energy Web Chain (with a portion mirrored on Ethereum mainnet). Token supply: ~98 billion SLR.
New
After: kSLR
1 kSLR per kWh of solar production on Base network. Conversion: 1 SLR = 1,000 kSLR (same value, different denomination).
Migration timeline.
Action required for custodial holders
1.
Snapshot — May 15, 2026
A snapshot of every SLR balance on Energy Web Chain and Ethereum mainnet is recorded. Your balance at the moment of snapshot determines your kSLR allocation.
2.
kSLR distributed — within days of May 15
kSLR tokens are minted on Base and claimable from the same wallet address via the migration portal. If you control your private keys, no action is required — your balance is mirrored automatically.
3.
New rewards begin
All new SolarCoin rewards are issued as kSLR on Base. Register or re-register your solar installation to start earning.
How to claim your kSLR, step by step.
Takes a few minutes. You do not need a crypto wallet to start — a wallet is optional.
Open the Claims Portal
Go to claim.solarcoin.org and create a free account with your email. No wallet, seed phrase, or crypto experience required.
Confirm your balance or register your solar
Existing SLR holder? Your May 15, 2026 snapshot balance is already recorded against your address — confirm it in the portal. New producer? Register your solar installation so future kSLR can be issued to you.
Choose where to receive your kSLR
Keep it in your managed account (nothing to set up), or connect your own wallet on the Base network if you prefer to self-custody. You can switch later.
(Optional) Add kSLR to your wallet
If you connected a wallet, use the one-click Add Base + import kSLR button on the Wallet page so your balance shows up automatically.
Done
Your kSLR is yours on Base. No rush — you have until May 15, 2027 (one year from the snapshot) to claim.
