Introduction

Smart contract development on any blockchain carries development costs covering resource expenditure. However, developing smart contracts on the TRON blockchain is vastly less expensive than Ethereum and similar protocols. This guide presents the comparison in a user-friendly format. If you wish to estimate energy costs for developing smart contract, please go to Tron Station which has energy and bandwidth tools can help you.

Summary

The tables below contrasts the development costs of small-sized contracts, a medium-sized contract, and a large-sized contract between TRON and Ethereum. The two example small contracts are a Simple Storage contract and a Fibonacci contract. The medium-sized contract example is a modified crypto-zombie contract called zombiefactory, while the large-sized contract is another modified crypto-zombie contract called zombieownership. The three cases in which bandwidth and energy consumption occurs are summarized as TRON-1, TRON-2, and TRON-3:

Table Denotes

TRON-1: not using any bandwidth or energy from frozen token
TRON-1 = Energy Fee + Bandwidth Fee
TRON-2: using free bandwidth or bandwidth from frozen token only
TRON-2 = TRON-1 - Free Bandwidth Quota - Frozen Bandwidth Quota
TRON-3: using bandwidth and energy from the frozen token
TRON-3 = TRON-2 - Frozen Energy Quota

For examples of freezing TRX for bandwidth and energy gain, please see the example code. For detailed descriptions of the HTTP APIs and TronWeb API functions, please visit the API reference.

How much TRX is needed to freeze to be free to deploy on main net?

Below number got from a test on the date of 10/23/2018, which TotalEnergyWeight was 2,127,263.

The energy we can get from freezing 100 TRX is = (100/2127263)*50,000,000,0000 = 23504380.

Energy obtained = the TRX frozen for gaining Energy / the total TRX frozen for gaining Energy in the entire network * 50,000,000,000

Based such amount of frozen token pool size,

to deploy a small contract we need to freeze 2-2.5 TRX to be free;
for a medium contract, 5-20 TRX used to freeze would be enough to be free deploy;
for a large contract, the number would be around 50 TRX.

Please notice that the energy obtains (energyLimit) is dynamic based on the totalEnergyWeight.
