Differences Between Eclipse and Solana
For the most part, developing and interacting with dApps on Eclipse is the same as Solana. However, there are some minor differences.
Native Token
The native token on Eclipse is ETH. It uses 9 decimal places, unlike Ethereum. You can get this token by bridging over ETH from mainnet Ethereum or from bridging over SOL or USDC from Solana. See our guide on how to do this here.
Similar to Solana, there are also wrapped versions of the native token for both the SPL Token and SPL Token 2022, both with 9 decimals as well. You can read more about the reasoning behind this here.
The addresses for these wrapped native tokens are the same as Solana:
SPL Token: So11111111111111111111111111111111111111112
SPL Token 2022: 9pan9bMn5HatX4EJdBwg9VgCa7Uz5HL8N1m5D3NdXejP
Priority Fees
Priority fees are paid in ETH, but follow Solana’s fee logic. When calculating priority fees using libraries like @solana/web3.js
, the units will still appear as micro-lamports, since the library is Solana-native. On Eclipse, 1 micro-lamport is interpreted as 1 kwei (i.e. 10^-15 ETH
), preserving equivalence with Solana’s fee structure while using ETH as the native token.
We recommend using getRecentPriorityFees
to dynamically fetch current fee rates instead of hardcoding values, as the USD-denominated cost of 1 micro-lamport (SOL) differs from 1 kwei (ETH).
Transaction Costs
Recent updates have significantly reduced the cost of transactions and account storage on Eclipse:
Lamports per Signature:
100
(↓ from 10,000) - 100x cheaperTransaction Fee Burn:
0%
(↓ from 50%)Rent per Byte-Year: 100x cheaper, mirrors the reduction in lamports per signature
Rent Burn Percentage:
0%
(↓ from 50%)
These changes make transactions and account creation dramatically cheaper than on Solana, while maintaining the same developer experience.
Wallets
You can find a complete list of Eclipse compatible wallets here.
dApps
Building dApps and deploying programs to Eclipse is the same process as with Solana. Just ensure any hardcoded program addresses exist on Eclipse. Please check this guide out for an example.
