# Ways to Buy SHELL

There are three ways to purchase SHELL tokens. The choice depends on your payment method and whether you prefer a graphical application or direct smart-contract interaction.

## Option 1: Accumulator Contract — Exchange eccUSDC Directly

**For:** advanced users and operators who already have eccUSDC (ECC\[3]) and want to submit the exchange transaction with `tvm-cli`.

**Interface:** the Accumulator smart contract on Mainnet/Shellnet.

**How it works:**

1. Prepare a wallet transaction containing a whole-number amount of eccUSDC
2. Send the transaction to the Accumulator contract with the required VMSHELL value
3. The contract exchanges eccUSDC at the fixed rate of 1 eccUSDC = 100 SHELL
4. SHELL is credited to the sending contract or to a recipient encoded in the payload
